Abstract
The study on ecological survey of plant species biodiversities and abundance in Southeastern Nigeria was conducted between January 2012 and 2013 at Anambra State, Nigeria to determine the plant species biodiversities and abundance in three forest fringes viz: community, shrine and reserves using measures based on floristic, stratified random sampling, plotless measure and point centre quarter methods, respectively. Shannon-wienners index of diversity analysis proved that Umunze community forest was highest in biodiversity (0.95) with Afzelia africana as the most dorminant species (148.93) while Pterocarpus sp. has the highest importance value index (25.36). Achala forest reserve has Chlorophora exdelsa as the most dominant (686.09), while Tectora grandis recorded the highest importance value index (62.53). The dominant species in Iyiocha forest was Pterocarpus species (451.31), while Newbouldia levis has the highest importance value index. Regression analysis showed that at P<0.05, there is a significant relationship between species abundance and species diversity. Key words: Ecology, survey, plants, biodiversities, abundance, Anambra.
Highlights
The scientific study of forest species and their interaction with the environment is referred to as forest ecology, while the management of forests is often referred to as forestry (Padoch et al, 1985). Primack (1991) noted that forest management has changed considerably over the last few centuries, with rapid changes from the 1980s onwards culminating in a practice referred to as sustainable forest management
Egboka (1993) stated that, Anambra is a state in the south-eastern Nigeria. °Its name is an anglicized version of the original 'Oma Mbala', the name of the river known as Anambra
Grandis becomes the abundant species of Achala forest reserve

Concentrate on forest patterns and processes, usually with the aim of elucidating cause and effect relationships. Foresters who practice sustainable forest management focus on the integration of ecological, social and economic values, often in consultation with local communities and other stakeholders (Primack, 1991)
