Question

During plant sampling, why quadrat of 1 m2 is preferred?

Answer 1

Answer:

hello dear,

Explanation:

Random sampling using quadrats

• When you have chosen a sampling area, first divide it up into a grid, for instance, having 10 × 10 divisions.
• Use a suitable method – you could draw numbers out of a hat – to generate a pair of random coordinates on your grid.
• Place the first quadrat on your grid using these coordinates.

Answer 2

During plant sampling, why quadrat of 1 m2 is preferred - True

Explanation:

• A quadrat is a framework, traditionally square, used to isolate a standard area unit for the distribution of an item piece over a wide area in ecology and geography. Modern quadrats may be rectangular, circular or irregular, for example. The quadrat is suitable for sampling plants , animals with slow movement and certain aquatic organisms.
• It would not be possible to count every organism if an ecologist needs to find how many organisms in a given habitat there is. Rather, a smaller representative part of the population known a sample would be used  to count. Plants can be sampled or animals that moves slowly (for example, snails) by a sampling square called a quadrat. Appropriate quadrature size depends on the sampling size of the organisms.
• Or for instance, a quadrat with sides of 0.5 or 1 metersquare in length could be used to count/sample plants growing in a school field. Selection of the square size largely depends on the type of survey carried out. For example, it would be difficult for a 0.5m2 quadrat study of a forest canopy to produce meaningful results.
