Native and alien plant species inventory and diversity in disturbed forests and its economic value
The study was conducted to assess the native and alien plant species in one of the highly disturbed forest (S1) and less disturbed forest (S2) in Mt. Manunggal, Cebu Island, Philippines. Twenty-four quadrats with a size of 20mx20 m were established using a quadrat sampling technique to identify and record all plant species. Diversity indices were utilized to determine species abundance, richnes...
متن کاملEvaluation of species diversity and spatial distribution characteristics of five dominant plant species in Hamoon wetlands
This research aimed to investigate plant species diversity and spatial distribution of five dominant species i.e. Phragmites australis, Tamarix meyeri, Aeluropus littoralis, Aeluropus lagopoides and Cynodon dactylon in Hamoon international wetlands in 2015. To this end, a randomize-systematic sampling method was used according to w pattern by four strip transect at 5000 m2 at each station. The ...
متن کاملPredicting species diversity in tropical forests.
A fundamental question in ecology is how many species occur within a given area. Despite the complexity and diversity of different ecosystems, there exists a surprisingly simple, approximate answer: the number of species is proportional to the size of the area raised to some exponent. The exponent often turns out to be roughly 1/4. This power law can be derived from assumptions about the relati...
متن کاملSilvicultural systems for southern bottomland hardwood forests
Silvicultural systems integrate both regeneration and intermediate operations in an orderly process for managing forest stands. The clearcutting method of regeneration favors the development of species that are moderately intolerant to intolerant of shade. In fact, clearcutting is the most proven and widely used method of successfully regenerating bottomland oak species in the South. The seed-t...
متن کاملEstimation of species diversity of trees and shrubs using ETM+ sensor data (Case study of forests in Qalajeh Kermanshah province)
The use of remote sensing techniques as a suitable solution to estimate the levels of species diversity is of high importance for the sustainable management of forests. In order to investigate the potential of using sensor data from Landsat 7 ETM+ to estimate species diversity in the Zagros forests, digital data related to the August 7, 2002 from forests in the Qalajeh Kermanshah Province were ...
