A low-cost UAV survey can unravel Baird's Tapir (Tapirus bairdii) trail network dynamics in a neotropical highland forest

UAV technology has transformed spatial data collection and high-spatial resolution analysis of diverse environments around the world. Its role within geosciences, ecology, engineering, and other sciences has been increasing withing the last decade. In ecological and geomorphological aspects, it offers a powerful tool for studying landforms, surface processes, vegetation, and animal behavior globally. Our study employs high-resolution UAV surveys to analyze Tapirus bairdii trail networks and their connection to the landscape in a Costa Rican highland paramo-forest national park. Using a DJI Phantom 4 V.2 UAV, we conducted a photogrammetric flight over 3.19 ha, producing datasets with a spatial resolution of 2.99 cm/pixel. These datasets facilitated geostatistical analysis of Tapirus bairdii trails, revealing their complexity and hotspots near lagoons. We investigated lagoon characteristics, finding that finer sediments spatially correspond with higher trail activity. This suggests that sediment types in lagoons influence Tapirus bairdii navigation, impacting trail network composition. Our findings highlight UAV technology's role in advancing ecological and geomorphological research in protected areas, providing insights into Tapirus bairdii behavior within highland ecosystems. Overall, to the date this is the first high-resolution UAV survey of Tapirus bairdii within these types of highland tropical environments.

Inter-annual variation in the microplastics abundance in feces of the Baird's tapir (Tapirus bairdii) from the Selva Maya, México

Microplastics (MPs) are found in a wide range of ecosystems, from the Arctic to the deep ocean. However, there is no data on their presence in terrestrial mammals that inhabit the Selva Maya. The aim of this study is to detect the presence of MPs in the feces of the Baird's tapir (Tapirus bairdii) from the region of Calakmul, located in the Yucatan Peninsula, Mexico. We analyzed 129 fecal samples collected during 2017 and 2018, obtaining 57 and 72 samples during the rainy and dry seasons respectively. Sixty-eight percent of the samples contained 743 MPs with a mean of 19.3 ± 28.1 MPs/kg of dry weight (DW) feces in both years. An inter-annual variation in the average abundance of microplastic was observed during the two-year period (2017–2018), with a 72 % increase in these plastic particles in feces. Fourteen polymers were identified, with ethylene vinyl acetate (EVA), polypropylene (PP) and polyester (PES) being the most abundant during both years. Although the effects of MPs on the health of tapirs are not known, their presence is cause for concern. There is an urgent need for the implementation of appropriate plastic waste management programs in communities of the Selva Maya to diminish the consumption of MPs in species including humans where they pose a significant risk to health. Environmental implicationsThe use of plastics worldwide is increasing every day, so the presence of microplastics is and will continue to be a major environmental problem. It is known that contaminants can adhere to plastics, making them hazardous materials. Microplastics can contaminate remote areas such as Biosphere Reserves. Terrestrial species such as the tapir can ingest microplastics, putting their health at risk. Knowing the dispersion of microplastics is very important in order to manage them properly, taking into account their emission sources and type of polymer.

Feelings, conflicts, and use: wildlife-human interactions in El Triunfo Biosphere Reserve, Mexico

ABSTRACT Human activities are one of the most critical threats to wildlife. Therefore, understanding human-wildlife interactions is key to designing and applying sound conservation strategies. We identified wild animals relevant for people in El Triunfo Biosphere Reserve, southern Mexico considering four types of interactions: Use, affect (either positive or negative), and conflict. Twenty-eight workshops and 670 wildlife-human experiences with 58 taxa were recorded. The most relevant species were Odocoileus virginianus, Tapirus bairdii, Panthera onca, Pharomachrus mocinno, and Bothriechis bicolor. Positive affect was the most frequent interaction reported (46%), followed by use (20%), conflict (17%), and negative affect (16%). Negative affect and conflicts were mainly related to fear and damage by native predators. Species use was relatively infrequent (20%). We propose that conservation strategies be directed according to the species and their specific interactions.

Inulin supplementation increases the differential metabolites and metabolic pathway in Baird's tapirs (Tapirus bairdii).

The prevalence of prebiotic has increased substantially over the past decades. Little is known on its metabolic effects in zoo herbivores. We investigated the difference in faecal metabolites to characterize the composition and pathways involved after feeding inulin in zoo Baird's tapirs (Tapirus bairdii). Faecal samples were collected from before inulin treatment group and after treatment groups in six adult tapirs and analysed using untargeted liquid chromatography-mass spectrometry methods. The differential metabolites identified and metabolic pathways involved were analysed using KEGG annotation. The results demonstrated significant alterations in faecal metabolites and metabolic pathways in comparison to the control group. The amounts of differential metabolites and metabolic pathways tended to enrich with time after the treatment. We found that tryptophan and purine metabolism were relevant to the important metabolic pathways of the metabolite differences. The findings suggest that inulin may have potential applications in captive wildlife, which may provide insights into the effects of prebiotic supplementation on gut metabolites and highlights further research in this field.

Predation of oak acorns by Baird's tapir in one of the last remnants of mountain cloud forest in Southern Mexico

The consumption of fruits and seeds by mammals can have a strong impact on the regeneration of tropical forests. Our knowledge of this biotic interaction has steadily increased recently but it remains fragmentary. This is largely due to most of the studies focusing on a small proportion of the diverse mammals and plants involved in these interactions and to the fact most commonly used methods provide just partial information about the whole seed dispersal/predation process. The use of camera traps has opened the opportunity to greatly improve our knowledge of the intricacies of frugivory and seed predation by increasing the likelihood to record very secretive animal species and providing detailed accounts of their behavior. Based on camera trap data we report acorn consumption of Quercus benthamii and Q. sapotifolia by the threatened Baird's tapir (Tapirus bairdii). This study was conducted in the largest remnant of Mountain cloud forest in Mexico, located in El Triunfo Biosphere Reserve (ETBR) in the state of Chiapas. Despite the fact that ten mammal species were recorded in the focal trees, only two of them (T. bairdii and Sciurus deppei) were documented exhibiting acorn consumption. We obtained 82 videos showing the consumption of Q. benthamii acorns by tapirs (sampling effort = 133 camera trap days, n = 8 trees) with an average of 6.04 ± 3.56 (± sd) minutes spent on this activity. In comparison, we only obtained one video of a tapir consuming Q. sapotifolia acorns (sampling effort = 264 camera trap days, n = 5 trees) during 35 s. Consumption of these Quercus species by tapir was not previously reported. Moreover, our study is the first (to our knowledge) to show video-recorded evidence of the interaction between tapirs and Quercus trees. Due to tapirs' large body size, the consumption of acorns might be an important source of mortality for some Quercus species (e.g., Q. benthamii).

Ticks (Parasitiformes: Ixodida: Ixodidae) parasites of wild Baird’s tapirs (Mammalia: Perissodactyla) in the Yucatan Peninsula, Mexico

ABSTRACT Tapirs are common hosts of ticks and an individual can be infested by up to seven different tick species. We explored the parasitic tick fauna associated with wild Baird’s tapirs (Tapirus bairdii) from the Yucatan Peninsula. A total of 326 ticks of 10 species of the Family Ixodidae were collected from 15 tapirs. We found a range of one to six tick species per host, but most of the tapirs were parasitized by two or three tick species. We tested the relationship between body condition, sex, and age classes of the tapirs versus the number of tick species on each host. The most common tick species was Amblyomma mixtum found on 93% of the hosts. Amblyomma pecarium, Amblyomma tenellum, Ixodes affinis and Rhipicephalus sanguineus sensu lato were recorded for the first-time parasitizing Baird’s tapirs. We did not find a relationship between body condition, sex, and age classes of tapirs versus the number of parasitizing tick species. Our finding demonstrates that the richness of ticks parasitizing tapirs does not depend on the biological characteristics and health status of the host, but could be determined by other factors such as habitat use and the rate of contact with domestic animals.

Effects of camera trap placement on photo rates of jaguars, their prey, and competitors in northwestern Costa Rica

AbstractThe use of camera‐trap methods, though important, has pitfalls and inconsistencies such as factors and interactions that may influence species photo rates. Jaguar (Panthera onca) camera‐trap studies place cameras at sites where jaguar detections are likely greater (e.g., sites with previous evidence such tracks, feces, and other presence signs), but do not account for potential placement biases. Our study evaluated methodological implications of a paired camera‐trap design at trail and off‐trail locations, and climate seasonality, on photo rates of jaguars, their prey, and competitors. From June 2016 to June 2017, camera traps were deployed at 58 different sites in a hexagon grid array of 3 km2 each in the Sector Santa Rosa (SSR) of Área de Conservación Guancaste in Costa Rica. Half of the cameras were located at a trail location that jaguars were likely to use, and the other half at an off‐trail location closest to each hexagon centroid. We estimated a photographic relative abundance index (RAI; no. of independent photos/100 trap nights) and used Generalized Linear Models (GLMs) to assess statistical evidence of trail location and climate seasonality. With a total effort of 19,408 trap nights, we recorded 12,678 independent photo events of 64 species of amphibians, reptiles, birds, and mammals. For the 3 bird species and 14 mammal species we focused on, most species‐specific RAIs were greater at trail locations (n = 8 species, including jaguars and pumas [Puma concolor]), some were greater at off‐trail locations (n = 2 species, including collared peccaries [Pecari tajacu]), and there was no discernable location effect for others (n = 7 species, including tapirs [Tapirus bairdii] and white‐tailed deer [Odocoileus virginianus]). For jaguars, sex ratio data showed a smaller proportion of males at off‐trail locations. Analysis of competitor and prey interaction data indicated temporal segregation at trail locations. Further jaguar camera‐trap studies should highlight camera placement as important source of bias that might influence results; hence, conservationists must be aware of this to avoid erroneous decisions.

Jaguar’s Predation and Human Shield, a Tapir Story

Despite the risks associated, some species choose to shield behind a predator to decrease predation risk by another predator. In this study, we demonstrate how Baird’s tapirs (Tapirus bairdii) use humans as a “shield” to reduce the risk of being preyed upon by jaguars (Panthera onca). We collected georeferenced photographic records of 23 tapirs (seven of them injured) sighted near human settlements (0 to 5 km) in the Calakmul region of Mexico from 2008 to 2019. Using multidimensional scale analysis, we determined which possible factors (tapir health status, injuries, distance to the settlement, as well as seasonality) are related to the decision of tapirs to approach human settlements. To support our claims of jaguars’ attacks, we described the pattern of injuries believed to have been inflicted by jaguars on tapirs, and we analysed photographs and videos of species of the genus Panthera attacking larger prey than themselves to establish a pattern of injuries and compare it to the injuries observed on tapirs. Our study shows that tapir sightings near human settlements are related to health deterioration, injuries by jaguars and seasonality. The injuries found on tapirs are similar to those caused by other big cats on large prey, providing strong support for jaguar-inflicted wounds. Further studies should investigate whether the increasing human presence in different habitats in the Neotropical region could be influencing the behaviour and distribution of prey and predators.

First genomic resource for an endangered neotropical mega-herbivore: the complete mitochondrial genome of the forest-dweller (Baird's) tapir (Tapirus bairdii).

Baird’s tapir, or the Central American Tapir Tapirus bairdii (family Tapiridae), is one of the largest mammals native to the forests and wetlands of southern North America and Central America, and is categorized as ‘endangered’ on the 2014 IUCN Red List of Threatened Species. This study reports, for the first time, the complete mitochondrial genome of T. bairdii and examines the phylogenetic position of T. bairdii amongst closely related species in the same family and order to which it belongs using mitochondrial protein-coding genes (PCG’s). The circular, double-stranded, A-T rich mitochondrial genome of T. bairdii is 16,697 bp in length consisting of 13 protein-coding genes (PCG’s), two ribosomal RNA genes (rrnS (12s ribosomal RNA and rrnL (16s ribosomal RNA)), and 22 transfer RNA (tRNA) genes. A 33 bp long region was identified to be the origin of replication for the light strand (OL), and a 1,247 bp long control region (CR) contains the origin of replication for the heavy strand (OH). A majority of the PCG’s and tRNA genes are encoded on the positive, or heavy, strand. The gene order in T. baiirdi is identical to that of T. indicus and T. terrestris, the only two other species of extant tapirs with assembled mitochondrial genomes. An analysis of Ka/Ks ratios for all the PCG’s show values <1, suggesting that all these PCGs experience strong purifying selection. A maximum-likelihood phylogenetic analysis supports the monophyly of the genus Tapirus and the order Perissodactyla. The complete annotation and analysis of the mitochondrial genome of T. bairdii will contribute to a better understanding of the population genomic diversity and structure of this species, and it will assist in the conservation and protection of its dwindling populations.

Abnormal morphology in Amblyomma coelebs and Amblyomma cf. oblongoguttatum (Acari: Ixodidae) collected on free-roaming Central American Tapir (Tapirus bairdii) from Nicaragua

In this work we describe abnormalities in Amblyomma coelebs and Amblyomma cf. oblongoguttatum adults collected from Tapirus bairdii. The observed anomalies in adults corresponded to general (asymmetry of scutum and idiosoma), and local malformation (atrophy and ectromely). This is the first record of morphological anomalies in A. coelebs and also it increases the observations of malformations in ticks from Nicaragua and Central America.

Human-wildlife conflicts and drought in the greater Calakmul Region, Mexico: implications for tapir conservation

Wildlife conservation efforts in the Mesoamerican Biological Corridor have focused on reducing negative interactions between humans and charismatic species. In recent years, droughts have increased in frequency and intensity in southeastern Mexico exacerbating conflicts with wildlife as they compete with humans for limited water. In the Yucatan Peninsula, Greater Calakmul Region of southeastern Mexico, Baird’s tapirs (Tapirus bairdii) are increasingly encroaching into local villages (ejidos) in search of water. This behavior could increase tapir mortality from hunting by Calakmul ejidos residents. We evaluated the trends between annual precipitation and tapir sightings near or within Calakmul ejidos from 2008 to 2019 to determine if the frequency of reported conflicts increased relative to decreased precipitation. In addition, with community participation, from 2016 to 2018 we monitored one of the ejidos where human-tapir conflicts were reported to be increasing to better describe the nature of conflicts. We did not find any relationship between the number of tapir sightings reported and annual precipitation. However, more tapirs were documented near ejidos in 2019, which is one of the years with the lowest rainfall (626.6 mm) in the last decade. Tapirs were reported as the most common wildlife species observed at waterholes (35.4%) and apiaries (32.1%). Our findings suggested that water scarcity has increased tapirs’ incursions into human-populated areas and subsequently the potential for human-tapir conflicts. We recommend that managers consider developing alternative water sources that could mitigate human-tapir conflicts and contribute to the long-term viability of other wildlife species that inhabit the Greater Calakmul Region of southeastern Mexico.

Tapirs in trouble: estimating Baird's tapir densities in the Sierra Madre de Chiapas, Mexico

AbstractSpatial capture–recapture models have been widely used to estimate densities of species where individuals can be uniquely identified, but alternatives have been developed for estimation of densities for unmarked populations. In this study we used camera-trap records from 2018 to estimate densities of a species that does not always have individually identifiable marks, Baird's tapir Tapirus bairdii, in the Sierra Madre de Chiapas, southern Mexico. We compared the performance of the spatial capture–recapture model with spatial mark–resight and random encounter models. The density of Baird's tapir did not differ significantly between the three models. The estimate of density was highest using the random encounter model (26/100 km2, 95% CI 12–41) and lowest using the capture–recapture model (8/100 km2, 95% CI 4–16). The estimate from the spatial mark–resight model was 10/100 km2 (95% CI 8–14), which had the lowest coefficient of variation, indicating a higher precision than with the other models. Using a second set of camera-trap data, collected in 2015–2016, we created occupancy models and extrapolated density to areas with potential occupancy of Baird's tapir, to generate a population estimate for the whole Sierra Madre de Chiapas. Our findings indicate the need to strengthen, and possibly expand, the protected areas of southern Mexico and to develop an action plan to ensure the conservation of Baird's tapir.

First Report of a Multidrug-Resistant ST58 Escherichia coli Harboring Extended-Spectrum Beta-Lactamase of the CTX-M-1 Class in a Fecal Sample of a Captive Baird's Tapir (Tapirus bairdii) in Costa Rica, Central America.

Objective: This study's main objective was to analyze the antibiotic susceptibility profile of Escherichia coli isolates obtained from a fecal sample of a captive Baird's tapir (Tapirus bairdii) in Costa Rica. Materials and Methods: The fecal sample was collected inside the enclosure on March 3, 2017, right after the animal defecated. Samples were cultured on MacConkey agar plates nonsupplemented and supplemented with 2 μg/mL of cefotaxime. Bacterial identification and antibiotic susceptibility were performed with the Vitek 2 Compact System and the Kirby Bauer disk diffusion method, respectively. Polymerase chain reaction amplification was performed to detect blaCTX-M beta-lactamase genes. Resistant isolates were subjected to whole-genome sequencing (WGS). Results: After evaluating several antibiotic classes, a multidrug-resistant E. coli strain with extended-spectrum beta-lactamase phenotype was isolated. Resistance to cefotaxime, cefepime, ampicillin, ampicillin/sulbactam, and tetracycline was detected. WGS analysis showed the presence of blaCTX-M-1, blaTEM-1B, and tet(B) genes. The presence of IncN plasmids and Col156 was also detected. Conclusion: Our findings are according with the notion that animals' high density enhances the spread of resistant determinants in a captive environment in a limited space, where the likelihood of direct or indirect contact with other animals and humans is more frequent.

Tapirus bairdii-Associated Fecal Microbiome from a Critical Conservation Area: Calakmul, México.

Baird's tapir (Tapirus bairdii) is the largest native terrestrial mammal in the Neotropics, which is endangered primarily as a consequence of habitat loss and overhunting. Baird's tapir is predominantly nocturnal and exists at low densities which complicates field studies. Baird's tapir is a large-bodied herbivore that plays a key role in maintaining healthy tropical forests through seed dispersal in its feces. Studies of gut microbiome are essential and valuable to assess the health status of the host and the interaction with the environment. In this study, we collected fresh fecal samples of T. bairdii to analyze its gut microbiome during the rainy and dry seasons in the Calakmul region, which is a critical rainforest conservation area in Mexico. The results of a high-throughput 16S rDNA gene sequencing approach suggest that the fecal microbiome of Baird's tapir has no significant differences in composition among seasons. The most common phyla were Firmicutes, Bacteroidetes, Proteobacteria, Kiritimatiellaeota, and Spirochaetes. This study suggests that the stability of the fecal microbiome is related to similar feeding strategies throughout the year, and emphasizes the value of tapir in seed dispersal (and associated microbes) to the well-conserved forests of the Greater Calakmul region as biodiversity hotspots for conservation.

First documented predation of a Baird’s tapir by a jaguar in the Calakmul region, Mexico

To date, records of predation on Baird’s tapir (Tapirus bairdii) by jaguars (Panthera onca) were anecdotal and did not allow for differentiation regarding whether the animal had been preyed upon or scavenged. Here, we present the first documented event of predation on a Baird’s tapir by a jaguar in the Calakmul region, Campeche, Mexico. In August 2017, we observed a jaguar eating a juvenile female Baird’s tapir; when we analysed the skull, we observed the characteristic “lethal bite” with which jaguars kill their prey by piercing the temporal and parietal bones with their canine teeth. Jaguars select to attack tapirs when they are most vulnerable (young or sick). Records of these type of events are important for understanding the food webs and ecology of these iconic Neotropical species that inhabit the Mesoamerican forests.

Survey of medium-sized and large mammals of Piedras Blancas National Park, Costa Rica

Piedras Blancas National Park, in southern Costa Rica, is an important component of two biological corridors connecting the Osa Peninsula (Corcovado National Park) and La Amistad International Park. Understanding the mammal community composition of Piedras Blancas will provide baseline data to evaluate the success of conservation efforts. We used camera traps and opportunistic observations to describe the medium-sized and large mammals of the park. We deployed camera traps for 1,440 trap nights (2016-2018). We detected 19 mammal species from seven orders and 13 families. Five species are globally threatened: Leopardus wiedii (Schinz, 1821), Saimiri oerstedii (Linnaeus, 1758), Ateles geoffroyi (Kuhl, 1820), Alouatta palliata (Gray, 1849), and Tapirus bairdii (Gill, 1865). We did not detect two locally threatened species, Panthera onca (Linnaeus, 1758) and Tayassu pecari (Link, 1795). Our research highlights a need for critical conservation work within the proposed biological corridor to support Costa Rica&amp;rsquo;s most threatened wildlife.

Human disturbance and the activity patterns and temporal overlap of tapirs and jaguars in reserves of NW Belize

AbstractHuman disturbance from tourism and other non‐consumptive activities in protected areas may be stressful to wildlife. Animals may move away in space or time to avoid human interaction. For species of particular conservation concern, such as Baird's tapirs (Tapirus bairdii) and jaguars (Panthera onca), a better understanding of how they respond to different levels and types of disturbance is needed in order to manage human visitation to parks in ways that minimize negative outcomes for wildlife. We describe the overlap in activity patterns of tapirs, jaguars, and humans at logged and unlogged sites and at places with low versus high human visitation using camera survey data from protected areas of NW Belize, 2013–2016. Tapirs were nocturnal in all study sites, with &gt; 80% of all tapir detections occurring between 1900 hr and 0500 hr. Their activity patterns were not different in unlogged versus logged sites and did not change with increased human traffic. Jaguars were cathemeral across sites but had more nocturnal activity at the site with the most human impact. Activity pattern overlap between tapirs and jaguars did not differ significantly between logged and unlogged sites, nor between areas with low and high human activity. Human traffic increased from 2013 to 2016 at most of the study locations. In conclusion, this camera trap dataset suggests that non‐consumptive human disturbance does not alter the activity patterns of tapirs and jaguars in protected areas lacking hunting pressure.Abstract in Spanish is available with online material.

Rapid defaunation of terrestrial mammals in a protected Neotropical cloud forest remnant

Macroecological analyses capture the widespread nature of wild mammal range contractions and population declines globally, with Neotropical rainforests particularly vulnerable. Yet there is a paucity of basic population biology data capturing local empirically observed population changes. We generated species-specific and aggregated temporal trends in populations of terrestrial mammals in Cusuco National Park, north-west Honduras testing the effects of body-size, hunting and zonal protection measures. Hunted species, regardless of body size, exhibited declines (ca. -7% per year) with greater rapidity of decline in the park’s more accessible and less rigorously protected buffer zone. The site was once regarded as a remaining strong of Baird’s tapir (Tapirus bairdii), IUCN Red Listed as Endangered, but our data suggest its near local extirpation from monitored sites. Hunted deer (Mazama temama and Odocoileus virginianus) and paca (Cuniculus paca) also declined substantially. Whilst species-specific trends varied among unhunted species (e.g. wild cats, mustelids etc.) they, nevertheless, also exhibited an aggregated decline throughout the park (ca. -6% per year). Such was the rapidity of these declines that we estimate substaintial mammalian defaunation of Cusuco National Park by the mid-2020s leaving a notionally highly protected area mostly devoid of terrestrial mammals and the associated ecosystem services they deliver (so-called ‘empty forest syndrome’). We call on Governments and non-governmental organizations including conservation charities to prioritize urgent efforts to secure funding and personnel to ensure designated areas are adequately protected with enforcement of existing legislative protection whether through patrols or capacity building to efficiently curtail ongoing defaunation.

Effectiveness of Panama as an intercontinental land bridge for large mammals.

Habitat fragmentation is a primary driver of wildlife loss, and establishment of biological corridors is a common strategy to mitigate this problem. A flagship example is the Mesoamerican Biological Corridor (MBC), which aims to connect protected forest areas between Mexico and Panama to allow dispersal and gene flow of forest organisms. Because forests across Central America have continued to degrade, the functioning of the MBC has been questioned, but reliable estimates of species occurrence were unavailable. Large mammals are suitable indicators of forest functioning, so we assessed their conservation status across the Isthmus of Panama, the narrowest section of the MBC. We used large-scale camera-trap surveys and hierarchical multispecies occupancy models in a Bayesian framework to estimate the occupancy of 9 medium to large mammals and developed an occupancy-weighted connectivity metric to evaluate species-specific functional connectivity. White-lipped peccary (Tayassu pecari), jaguar (Panthera onca), giant anteater (Myrmecophaga tridactyla), white-tailed deer (Odocoileus virginianus), and tapir (Tapirus bairdii) had low expected occupancy along the MBC in Panama. Puma (Puma concolor), red brocket deer (Mazama temama), ocelot (Leopardus pardalis), and collared peccary (Pecari tajacu), which are more adaptable, had higher occupancy, even in areas with low forest cover near infrastructure. However, the majority of species were subject to ≥1 gap that was larger than their known dispersal distances, suggesting poor connectivity along the MBC in Panama. Based on our results, forests in Darien, Donoso-Santa Fe, and La Amistad International Park are critical for survival of large terrestrial mammals in Panama and 2 areas need restoration.
