I have started identifying the species in our property to hopefully later on enumerate all the species found in the area. Our area can already be the sampling unit to represent the species richness in our municipality. Biodiversity or Species Diversity Index can also be computed when data proved sufficient. There are authorities in this field here in the country, but specific vulnerable areas, endangered or protected areas are the subject of concern. In the case of private properties like ours, I will start on my own biodiversity enumeration. Simultaneous with that i am also trying to enumerate the butterflies. Of course, i am asking help from some friends for identification because i am not a taxonomist in forestry, botany or entomology. I am a horticulturist so i can on my own handle the fruits and vegetables identification.
A formula in finding Biodiversity Index to describe the amount of species diversity in a given area is being used by scientists. An example of a simple Biodiversity Index is calculated as follows:
the number of species in the area (numerator) / the total number of individuals in the area (denominator)
= Biodiversity Index
Example 1. a 4X4 meter square area in a carrot patch has 300 carrot plants, all the same species. It has a very love biodiversity index of 1/300 or 0.003
Example 2. a 4X4 meter square area in the forest has 1 pine tree, 1 fern, 1 conifer tree, 1 moss, and 1 lichen, for a total of 5 different species and 5 individuals. The biodiversity index here is high, 5/5=1. REFERENCE
A more complicated formula is given by the Simpson's Diversity Index (REFERENCE)
|n = the total number of organisms of a particular species|
|N = the total number of organisms of all species|
This is the biodiversity site at the back of our property, just a few meters from our house. I was so amused at this photo because of the animal-looking structure at the center, made so by the vines constricting a tree branch. This area is just like an oasis between farmed areas, and give sanctuary to insects, reptiles and birds. How would you like a secondary forest like these near your house?

Mt Tore as shot from Mt Gulugod Baboy. Thicker vegetation is found in these areas as it is not easily accessible to cattle grazers and tourist campers.
