calculation

These are some that u guys need to calculate in your report.

Species frequency

-measure of the probability of finding a given species in any quadrat. Value in terms of %.

- just the measure whether the organism is presence or absence

Eq. if 10 quadrats are studied, species x is found only in quadrats 3,7, and 9:

% frequency= 3/10 x 100 = 30%

Species density

-number of individual of a given species in a given area

-provide accurate and absolute measure of abundance but a bit of time consuming. (we did this)

-usually express as average number of individual persquare metre.

Eq.

Quadrat ( 1m² )	1	2	3	4	5	6	7	8	9	10
Number of plant P	12	18	0	2	22	15	3	5	13	0

Density of species P = 12+18+0+2+22+15+3+5+13+0

10 x 1m²

= 10plant/m²

Species cover

-% of the ground covered by a species within the area of sampled. It is a useful way of estimating the relative contribution of the diff species in a community, especially when it is difficult to count individual plants.

% cover = total base cover/ arial cover of species in all quadrat x 100

Area of 1 quadrat x total number of quadrat

*we don’t calculate this. And u must be able to explain why. (find it on ur own)

Relative density, relative cover, relative frequency

Relative density = density of particular species / total density of all species x 100%

Relative cover = cover of particular species / total cover of all species x 100%

Relative frequency = frequency of particular species / total frequency of all species x 100%

*the unit for humidity is gram per cubic meter air ( gmˉ³ of air )

* hope u can do ur report ok… if anything about the report then text me a message… but not to the extend of how to do it… hehe tq…
