METHODS FOR ESTIMATING BIOMASS


BIOMASS DENSITY BASED ON EXISTING VOLUME DATA

This method is utilized when there is a defined volume per data and is used primarily for closed biomes.
 The Equation is:
Aboveground biomass density (t/ha) = VOB * WD * BEF
where:
WD = volume-weighted average wood density (1 of oven-dry biomass per m3 green volume)
BEF = biomass expansion factor (ratio of aboveground oven-dry biomass of trees to oven-dry biomass of inventoried volume)

 BIOMASS DENSITY BASED ON STAND TABLES
In this method different tables with regression equations to estimate the biomass density.

Biodiversity Index

A biodiversity index is used to measure the number of species and subspecies in a biome. The 3 main types of index are:

Simpson index: This index measure the species richness and the % of the subspecies in a sample area, this proportion define the importance of a specie in a biome. 

Shannon-Wiener index: Also called Shannon index, this type of index is really similar to Simpson`s. It measures the subspecies and its proportion in a specific zone. Simi

Barker-Parker index: This index only uses the information of the main species in a certain zone.

In this blog I'm gonna give my opinion about several aspects of earth and it's care that are essencials to me and should be essential to you.  


A system can have many definitions:

¨A collection of components that act in a predictable way
¨Assemblage of parts and their relationship forming a functioning whole”
¨These components  can be isolated and studied
¨The environment is a number of interacting systems both living and non-living.


In our world there are many different types of ecosystems like:

  • The trophic level is the hierarchal position that an organism or group of organisms occupies in an ecosystem, also called feeding levels
