Changing fire regimes during the first olive cultivation in the Mediterranean Basin: New high-resolution evidence from the Sea of Galilee, Israel

Throughout the Mediterranean biome, fire has been a dominant natural agent of change and an important tool for anthropogenic landscape modifications for millennia. However, fundamental knowledge on the complex linkages among fire, vegetation, and early agricultural practices remains limited. This research explores the role these processes have in shaping the landscape in the southern Levant – a key region with a long tradition of agriculture and horticulture. Olive horticulture is among the oldest and most widespread agricultural forms in the Mediterranean Basin. The earliest palynological evidence for olive horticulture is recorded in the Sea of Galilee in Israel and suggests that the first major olive cultivation began during the end of the 8th millennium BP. We present a multi-proxy dataset from the Sea of Galilee before and during the first olive cultivation (~7700–6680 a cal BP). Quantitative analyses of a charcoal time series categorized into distinct charcoal morphotypes indicate changes in fire regimes and sources of biomass burning. With a two-year-resolution, our study offers one of the highest resolution sedimentary charcoal records yet available worldwide. Isotopes from lake carbonates provide new evidence for the climatic setting of this phase, providing an independent evaluation of climatic impacts on vegetation and fire. Combined with palynological evidence, this multi-proxy dataset provides new insights into the linkages between fire, climate, fuel, and early horticultural practice. The fire regime changed with the start of olive cultivation in the Sea of Galilee's catchment. Fire frequency increased just before and during the expansion of olive cultivation, probably driven by the anthropogenic use of fire for clearing the landscape and promoting fertile soils. Once olive orchards were established, low magnitude fires became common, suggesting anthropogenic manipulation of the fire regime with frequent, low intensity, controlled burnings. Fuel limitation and low fuel connectivity likely played a role in both pre-cultivation and cultivation phases, resulting in low fire activity during times of reduced grass and woody vegetation cover. This study allows a new perspective into the temporal variability of middle-Holocene fire regimes in the Levant and an increased understanding of the dynamic role of fire during early horticulture practices. Our data also have relevance for future challenges that cultural legacies such as olive cultivation will face.

Horticultural practices based on brihatsamhita

India is a nation having rich knowledge regarding its traditional methods of agriculture. Ancient Indian text such as Varahamihira’s Brihatsamhita provides indigenous knowledge. It contains a chapter called ‘Vrksayrveda’ mainly deals with horticulture. It has given importance on gardening and water tanks. Regarding nutritional care, it has fully organic and time tested methods to deal with entire plant life. It has also described various grafting techniques. Vrksayurveda has also recommended planting distances for trees. Just as the human body plants are also affected by various diseases so treatment of these diseases of plants i.e. phytopthology can be studied in Vrksayrveda following the knowledge of factors, symptoms of affected plant and treatment protocol. Treatment of seeds is highly essential to prevent infections, pest attacks and for quicker germination. Vrksayurveda describes various practices of sowing seeds, instant sprouting and fruting. In the presence study, various horticultural practices based on Brihatsamhita are discussed.

Fluazinam and its mixtures induce diversified changes of crucial biochemical and antioxidant profile in leafy vegetable

Fungicides applied singly are frequently used to ensure disease control in the cultivation of leafy vegetables. The behavior of fungicide mixtures and their impact on plant biochemical and antioxidant status was poorly investigated. The main goal of this study was to compare the impact of fluazinam, a separately applied fungicide, and its mixtures (dithianon+fluazinam, dodine+fluazinam) during dissipation on biochemical compounds and the antioxidant profile in lettuce. Additionally, the behavior of dithianon and dodine applied singly was examined. We noted a longer dissipation time of fluazinam in mixtures (DT50= 6.31 and DT50=4.80) compared to separate application (DT50= 3.36) as well as a shortened dithianon and dodine degradation in mixtures. Moreover, dithianon, dodine and fluazinam applied separately affected the reduction of chlorophylls (43%) and carbohydrates (56%) as well as the induction of carotenoids (37%), protein (40%) and phenolic compounds (50%) in a different dissipation time. Furthermore, fluazinam mixtures intensified accumulation of carotenoids (up to 106.1 µg g−1), protein (21.9 mg g−1) and phenolic compounds (1410 µg g−1), while reduction of carbohydrates (3.4 µg g−1), compared to separate application. For the first time, we revealed that non-enzymatic antioxidants are the first line of defense in ROS scavenging caused by fungicides (up to the 12th h), while antioxidant enzymes (CAT, POD, SOD) play a secondary role in supporting stress mitigation. Results of the study can be applied to the horticultural practice in lettuce cultivation and shed a new light on plant biochemistry under fungicide stress conditions.

Growing roses without chemicals: transitioning the collection at Auckland Botanic Gardens (New Zealand) 2000–2020

The Rose Garden at Auckland Botanic Gardens displays rose cultivars which perform well and remain healthy in Auckland, New Zealand, without pesticide applications. Miticides, insecticides and fungicides are not used. Suitable cultivars are chosen for public display to inspire gardeners and encourage visitors to make their own rose selections based on personal preferences from an array of proven performers. These are identified to the public as ‘Star Performers’. Here the process of trialling, identifying and displaying old shrub and modern rose cultivars that have achieved Star Performer status over the past 20 years is presented. This work demonstrates the role that botanic gardens can play in promoting sustainable horticultural practices.

Critical Issues in Consumer Horticulture: Gaps in Research and Public Gardens’ Involvement in Consumer Horticulture

The retail gardening industry in the United States is expected to reach $50 billion by 2023, and it is a significant driver of the agricultural economy. To meet the corresponding demand for information, consumer horticulture (CH) professionals will need to develop innovative digital outreach, research-based solutions, a concerted recruitment of youth, and enhanced collaborations. To understand the current gaps in CH research and the extent of the involvement of public gardens in CH, surveys were conducted among the two groups, CH/extension researchers and staff of public gardens. The results of the surveys were presented at the virtual conference of the American Society for Horticultural Science on 12 Aug. 2020 during a workshop hosted by the Consumer Horticulture and Master Gardener Professional Interest Group. The workshop included four presentations, and two of those are discussed in this paper: 1) research gaps in CH and 2) bridging the divide between CH and public gardens. Among researchers, even though there was a general understanding of CH, there was a disconnect in participants’ perceptions of the roles of CH in the economy and recreation. The greatest knowledge gap was in basic horticultural practices. Regarding public garden professionals, there needs to be a concerted effort to educate them about CH so they can provide a consistent message to their audiences and the general public.

Carbon Sequestration in Mango Orchards in Seasonally Dry Tropical Savanna Climate under Different Management

ABSTRACT This study assessed the carbon (C) sequestration potential of 35-year-old mango orchards under different management. Potential C-sequestered was estimated in various C pools, viz., above-ground biomass (AGB), below-ground biomass (BGB), weed, litter, and soil organic carbon (SOC). Mango trees under conservation horticultural practices (CHP) had the highest values of AGB and BGB, 382.13 kilogram (kg) tree−1 and 115.25 kg tree−1, respectively, whereas AGB and BGB were lowest in mango trees with weed cover and intensive management (WCIM) (328.69 kg tree−1 and 99.13 kg tree−1, respectively) and intermediate in mango orchards with clean cultivation and intensive management (CCIM) (342.51 kg tree−1 and 112.26 kg tree−1, respectively). Mango orchards with CHP and WCIM expressively enhanced the soil C stock in the top 1 meter (m) of orchard soils. Compared to clean a cultivation vegetable field (CCVF), CHP and WCIM increased soil C sequestration by 15.2 tonnes per hectare (t ha−1) and 12.9 t ha−1, respectively. Soil C is the largest pool of C followed by AGB, BGB, and litter ≥ weed. Soil C had 2.54-, 2.75-, and 2.37-fold higher CCIM, WCIM, and CHP, respectively, than tree C. The highest total C content (107.63 t ha−1) was found in CHP, followed by WCIM (100.05 t ha−1), and the least was under CCIM (97.31 t ha−1), suggesting that mango orchards with CHP offer promising potential for total C sequestration. Averaged across the three different management systems, the highest potential for C storage was observed to be 101.7 t ha−1 for mango orchard, 1.68 fold higher than in vegetable systems.

Thinning Methods to Regulate Sweet Cherry Crops—A Review

In perennial fruit crops, bearing can be influenced by various factors, including environmental conditions, germplasm, rootstocks, and cultivation methods. Cherries, one of the most important and popular fruit species from the temperate climate zone, achieve high prices on the market. New agricultural technologies and environmental factors force a change in the approach to cherry cultivation. Old-type cherry orchards, with their high demand for water, nutrients, and manual work, are replaced by orchards of self-pollinating cherry cultivars grown on dwarf rootstocks. These changes make it necessary to search for ways to regulate fruiting, in particular to thin buds, flower, and fruit. In light of environmental regulations and consumer pressure, thinning methods are being sought that either do not involve the use of chemicals or that use eco-friendly chemical agents. This review examines recent progress in understanding the effect of thinning methods on the physiology, tree growth, and fruit quality of cherries; discusses horticultural practices aimed to ensure regular cropping and their influence on fruit quality; and provides suggestions for future research.

Remote sensing and soil moisture data for water productivity determination

This work was initiated in 2019 within the FAO WEPS project framework (2018–2022), aiming to determine the Water Productivity (WP) of the Tunisian olive orchards combining two scales of measurements for soil moisture determination: one for the global analysis (remote sensing) and the other for the field scale application. The experiment was made in 2019 and 2020 in the Centre of Tunisia (Kairouan city, locality of Elhouereb), which is one of the largest irrigation area of Tunisia. WP was computed regarding the actual crop evapotranspiration (ETa) which was determined following the water balance method as: ETa=R+I–ΔS, where ΔS is the amount of water stored in the soil (0–60 cm) and (R) and (I) are the amounts of the seasonal rainfall and the irrigation volume, respectively. The annual ETa reached 293 mm for the rainfed orchard, 823 mm for the semi-intensive irrigated plantation and 819 mm for the intensive fertigated orchard. The WP defined as being the ratio of Yield (kg olives/tree)/ETa ranged between 0.29 kg/m3 (rainfed) and 0.77 kg/m3 (fertigated) depending on the cultivation system. Soil moisture was found to be correlated to the average backscatter coefficient (r = −0.34 for the rainfed and 0.91 for the irrigated orchards) which was determined from the radar images which were treated by using different applications (SNAP, ODK, QGIS.), This result shows the performance of the remote sensing tools for such application. To conclude: WP is at least two times higher in the irrigated orchards than in the rainfed grove; this indicates a great potential of WP improvement if the horticultural practices are well applied in the orchad (pruning, irrigation); so that, the WP can be used as a decision-making-tool for farmers and makers in the future.

Response of Plant Growth and Development, and Accumulation of Hydroxyl-cinnamoyl Acid Derivatives to Selected Shade Nets and Seasonality of Field-grown Bush Tea (Athrixia phylicoides DC.)

Horticultural practices and quality of bush tea (Athrixia phylicoides DC.) are critical for herbal tea industrialization. The objective of the current study was to determine the effect of selected shade nets and seasonal variation on plant growth and development, and hydroxycinnamic acid content of field-grown bush tea. The trial was laid out in a randomized complete block design consisting of three shade nets (black, green, and white) and control or full sunlight with three different light intensities (40%, 50%, and 80%) replicated three times. Proportion of intercepted radiation by the canopy, chlorophyll content, plant height, and fresh and dry mass were measured, and hydroxycinnamic acid accumulation was determined. In addition, hydroxycinnamic acid composition was determined using liquid chromatography linked to mass spectrometry (LC-MS). The application of shade nets resulted in plant growth and yield reduction as compared with the plants exposed to full sunlight during summer followed by white shade net. The accumulation of hydroxycinnamic acid was higher in 80% white shade net plots compared with unshaded plants (control) and the other shade nets. Therefore, lack of shading provides a conducive environment to enhance plant growth and development of bush tea. The white shade net (80%) was an effective microclimate tool to enhance accumulation of caffeoylquinic acid (m/z 353), p-coumaric acids (m/z 337), dicaffeoylquinic acid (m/z 515), and tricaffeoylquinic acids of bush tea. This study is the first to demonstrate light as a determining factor for production of chlorogenates in bush tea plants. Future studies will be conducted to determine the effect of light on extracts of the bush tea using different solvents.

Reduction of Early Fruit Abscission by Main-branch-girdling in Macadamia Is Related to the Favorable Status of Carbohydrates and Endogenous Hormones

Fruit abscission occurring severely in the early fruit development affects macadamia yield. Developing effective methods to improve fruit retention is a priority for macadamia cultivation and production. Girdling is an important horticultural practice that has been widely used to increase fruit yield. Previous studies have shown that girdling fails to increase macadamia yield despite enhancing the early fruit set, but few have examined the effect of girdling on its related physiological mechanism. The objective of this study was to investigate the effects of main-branch girdling (MBG) on early fruit retention and also on the levels of carbohydrates and endogenous hormones in the leaves, bearing shoots and fruit of macadamia. Herein, MBG was performed at fruit set using a single-blade knife on 9-year-old macadamia trees (Macadamia integrifolia). Results showed that MBG significantly reduced young fruit drop, concurrent with significant increases in the contents of starch in both the leaves and the bearing shoots and in glucose, fructose, and sucrose levels in the husk and seed. It was suggested that the availability of carbohydrate for fruit retention was improved by MBG. Additionally, MBG increased indole-3-acetic acid (IAA), gibberellin (GA3), and zeatin-riboside (ZR, a type of cytokinin) concentrations and decreased abscisic acid (ABA) contents in the husk and the seed, indicating that MBG reduced the early fruit drop by modifying the balance of endogenous hormones. Therefore, a positive interplay between carbohydrates and endogenous hormones induced by MBG was involved in the reduction of early fruit abscission in macadamia.

Morphophysiological response of young Frantoio olive tree under different fertilizer types in sierozem with surface drip irrigation

The amount of yield and adaptation of a cultivar to a new environment is strongly related to nutrient uptake ability. This study was carried out during 2019, 2020 and 2021 seasons to investigate the effect of different forms of chemical compose 20.20.20 fertilization alone or incombination with other fertilizers on morphological plant parameters (number of leaves per shoot, stem length and stem thickness) and leaf nutrient contents (N, P, K and Mg) of young Frantoio olive tree grown in Turkestan region, South Kazakhstan. The study was conducted on 1 years old olive trees of Frantoio in sierozem, under surface drip irrigation, system and uniform in shape and received the common horticultural practices. It was determined that fertilizer treatments significantly influenced number of morphological plant parameters and leaf plant nutrients compared to control treatments at all seasons. Results revealed that all fertilizers as well as the combination between 20.20.20 and Biohumus treatment and/or Nitroammophos treatment significantly increased morphological plant parameters and nutrient contents of young Frantoio olive trees. It can be concluded that the variation in the nutrient uptake ability may be used as a criterion for adaptation of a variety to a new ecological environment.

Achieving the Social Wellbeing Through Urban Horticulture Practices for Food Production and Security: A Comprehensive Review of Perception-Based Studies

Achieving the Social Wellbeing Through Urban Horticulture Practices for Food Production and Security: A Comprehensive Review of Perception-Based Studies

Synchronized flowering in pomegranate, following pruning, is associated with expression of the FLOWERING LOCUS T homolog, PgFT1.

Flowering in angiosperms is a crucial event that marks the transition from the vegetative to the reproductive phase. In many perennials, pruning is an important horticultural practice that induces synchronized and profuse flowering. In pomegranate, vegetative growth immediately after pruning is associated with activation of PgCENa, a flowering suppressor of the phosphatidyl ethanolamine binding protein (PEBP) family, while a reduction is associated with synchronous flowering. We show that flowering in pomegranate is activated by expression of another PEBP family member, PgFT1, a homolog of the FLOWERING LOCUS T (FT) gene that promotes flowering. PgFT1 shows a rapid reduction in expression during the extensive vegetative growth immediately after pruning but shows robust expression during synchronous flowering post-pruning, in flower-bearing shoots but not in branches that do not bear flowers. A continuous low-level flowering in the absence of pruning is associated with continuous but reduced expression of PgFT1. Flowering by heterologous expression of PgFT1 in Arabidopsis is affected by a single amino acid change in the C-terminal region of PgFT1, which upon correction, promotes flowering in Arabidopsis. Our study provides insights into the molecular mechanisms by which pruning affects flowering pathways in tropical perennial fruit plants such as pomegranate.

Impact of climate change on fruit and vegetable crops and its mitigation strategies

The biggest challenge to humanity in the twenty-first century is global warming and climate change. Climate change reduces production and efficiency, while also increasing environmental stress on fruit and vegetable crops. Increased temperature, decreased irrigation water supply, flooding, and salinity are thought to be the limiting factors in improving fruit and vegetable productivity. The melting of the Himalayan ice cap would minimise the cooling effect needed for the flowering of many horticultural crops such as apples, saffron, rhododendrons, and orchids, among others. Commercial horticulture plant development especially that grown in open fields will be severely harmed. Integrated approaches such as fertiliser and tillage, residue management, water management, mulching, enhanced pest management, and breeding approaches such as production of genotypes resistant to high temperatures, salinity, modification of current horticultural practices, and increased use of greenhouse technology are to be adopted. Conservation agriculture, renewable energy, forest and water conservation, reforestation, and other methods are the most important.

Multi-dimensional leaf phenotypes reflect root system genotype in grafted grapevine over the growing season.

BackgroundModern biological approaches generate volumes of multi-dimensional data, offering unprecedented opportunities to address biological questions previously beyond reach owing to small or subtle effects. A fundamental question in plant biology is the extent to which below-ground activity in the root system influences above-ground phenotypes expressed in the shoot system. Grafting, an ancient horticultural practice that fuses the root system of one individual (the rootstock) with the shoot system of a second, genetically distinct individual (the scion), is a powerful experimental system to understand below-ground effects on above-ground phenotypes. Previous studies on grafted grapevines have detected rootstock influence on scion phenotypes including physiology and berry chemistry. However, the extent of the rootstock's influence on leaves, the photosynthetic engines of the vine, and how those effects change over the course of a growing season, are still largely unknown.ResultsHere, we investigate associations between rootstock genotype and shoot system phenotypes using 5 multi-dimensional leaf phenotyping modalities measured in a common grafted scion: ionomics, metabolomics, transcriptomics, morphometrics, and physiology. Rootstock influence is ubiquitous but subtle across modalities, with the strongest signature of rootstock observed in the leaf ionome. Moreover, we find that the extent of rootstock influence on scion phenotypes and patterns of phenomic covariation are highly dynamic across the season.ConclusionsThese findings substantially expand previously identified patterns to demonstrate that rootstock influence on scion phenotypes is complex and dynamic and underscore that broad understanding necessitates volumes of multi-dimensional data previously unmet.

Automated ebb-and-flow subirrigation accelerates citrus liner production in treepots

Over the past decade, citrus production has sharply decreased in Florida because of citrus greening or Huanglongbing (HLB), a disease that reduces fruit yield and quality and eventually kills the citrus trees. With the increased mortality and need to resetting trees, the demand for healthy trees from citrus nurseries has risen drastically in the last few years. To meet the demand and accelerate tree growth, the citrus nursery industry should use modern horticultural practices such as more efficient irrigation methods, fertigation, and more vigorous rootstocks. This study evaluated the effect of subirrigation systems in tree production time, water and fertilizer inputs, and plant growth of commercial citrus rootstocks cultivated in treepots. We tested five irrigation methods [three ebb-and-flow subirrigation systems triggered at specific volumetric water contents (θ, 0.24, 0.36, and 0.48 m3 m−3), capillary mats, and a conventional drip irrigation system], and six commercial rootstocks (Kuharske, UFR-2, UFR-16, US-802, US-812, and X-639). The experiment was arranged in a split-plot design, with the main plot consisting of the five irrigation methods and sub-plots the different rootstocks. Ebb-and-flow subirrigation benches conserved 98% more water than conventional drip irrigation. Rootstocks grown under ebb-and-flow systems reached adequate stem diameter for grafting four weeks before the drip irrigation. Pummelo hybrids used in this study (UFR-16, UFR-2, and US-802) were 55% taller, 24% thicker, and 150% heavier on biomass production than the other varieties tested, irrespective of the irrigation method utilized. Although the substrate electrical conductivity was higher in all subirrigation methods, the values were below 1 dS cm−1, not causing symptoms of osmotic stress in plants. Our results show that the ebb-and-flow subirrigation system at θ of 0.24 m3 m−3 is the best option for accelerating citrus growth in treepots with peat: perlite substrate and to conserve water in Florida nurseries in comparison to capillary mats and drip irrigation.

Amalgamation of Nanotechnology with Plant Sciences

This review paper deals with the basic aspects and advancement of Nanotechnology and its varied applications in every possible field starting from biotechnology, pharmaceuticals, drug science energy related sectors and so on. They show some explicit properties like strength, electrical, optical and chemical properties. Nanoparticles show increment in plant productivity by showing direct interactions with plants or indirectly with soil. Nanoparticles can easily be synthesized utilizing microbes and plants so they are organically protected, savvy, and climate amicable. Nanoparticles are termed as “magic bullets” because of their extraordinary properties, and for this reason they are employed in production of nano herbicides, nano pesticides. Nanotechnology does the job of addressing distinctive natural and medical problems which occurs to happen with the unreasonable utilization of pesticides and fertilizers in horticultural practices. When used in an appropriate amount and concentration they cause positive effects on the respective plants. Some of these include increment in crop production, better quality, increased photosynthetic activity, biomass, chlorophyll content and the list go on. With every positive effect comes the detrimental ones also. Inhibition of root and shoot length, reduced seed germination, inefficiency in photosynthetic activity.

Biostimulants containing amino acids in vegetable crop production

Amino acids can induce defence reactions and reduce the impact of abiotic stresses on plants, yet their impact on the yield of vegetable crops is varied. For this reason, an analysis of the published research on the effect of biostimulants containing amino acids (BCAA) on the quantity and quality of vegetable crop yield was carried out. The results of the research indicate the multidirectional effect of BCAA on vegetable plants and they also show that the use of these biostimulants may increase yield quantity and quality as well as influence biometric features and chemical composition of plants. BCAA may also affect the amount of losses caused by pests and during the storage of vegetables. However, the variability of the effects is very large and depends on many factors: composition of BCAA, time, dose, number and method of application, cultivation cycle, weather conditions, and plant species or even cultivar. Therefore, the effective use of BCAA requires further research, while their proper application in horticultural practice will require taking into account many factors.

Changing Farmers' Perception towards Sustainable Horticulture: A Case Study of Extension Education in Farming Community in Yogyakarta, Indonesia

Applying sustainable horticulture as an innovation in The Special Region of Yogyakarta (DIY) Indonesia can be a commendable example in agricultural extension education. Previous research has revealed that understanding farmers' perceptions of innovation is essential for appropriate interventions to change their behavior. In DIY, the surveys were conducted in 2016 with 257 males and 93 females of farmers groups member from 21 villages in Sleman, Bantul, and Kulonprogo Regency. The objective of the survey was to determine the effects of farmer's internal factors on the perception of ecological, social economy, and ethical (ESE) urgency as a component of sustainable horticulture practices. The findings from the ecological, social, and ethical dimensions among the farming community in DIY indicated that, directly and indirectly, the farmers can acknowledge and practice sustainable horticulture. However, this was altering several factors, most notably, motivation and the prospect of increased income. The important thing in extension work was motivation, and a major motivating factor was the possibility of increased agricultural income. This study suggests that extension education of achieving horticultural sustainability in DIY should be based on the motivation of farmers and thoughtfulness of their basic needs especially needs to have higher income.

New approaches for revegetating agricultural landscapes to provide connectivity for wildlife: The example of the Tasmanian Midlands, Australia

SummaryThere is an ongoing search for cost‐effective, practical and successful methods for landscape‐scale restoration required to meet the challenges posed by the United Nations Decade on Restoration 2021–2013. Mechanised cultivation techniques (rip mounding and Wilco spot cultivation), a range of revegetation strategies (dense reafforestation, riparian corridors, vegetation islets and scattered tree plantings) and best horticultural practice were employed to successfully establish extensive areas of local native trees and shrubs in highly altered agricultural landscapes within the Midlands of Tasmania, Australia. This region has been intensely farmed for the last 200 years and is characterised by past failures in native tree plantings. Between 2009 and 2018, 1800 ha were revegetated with a suite of hardy local native species to enhance, buffer and connect native vegetation remnants. These techniques were applied at a landscape scale to create biodiversity corridors that crossed the Midlands. Riparian corridors 100–200 m wide were created along 21 km of riverbank at an average density of 440 stems/ha. Fenced vegetation islets and individually caged scattered trees were established within and surrounding native vegetation remnants, at an average density of 143 stems/ha. Whole paddocks were densely reafforested at up to 800 stems/ha. Despite this, re‐establishing structurally complex and species diverse native vegetation, which can provide habitat for local native animals, proved challenging. In areas highly altered by a long history of farming, repeated interventions and long‐term relationships with landholders will be needed to achieve restoration objectives.
