In light of the above statements, choose the correct answer from the options given below
Given below are two statements
Statement I: Agroforestry systems tend to be more resilient than conventional agriculture to environmental shocks and the effects of climate change.
Statement II: Depending on the system and local conditions, agroforestry can achieve 50–80 per cent of the biodiversity of natural forests; increase food security and nutrition by serving as a safety net, and increase crop productivity.

The age of a felled tree can be determined only if the stump shows distinct ______________.
Diameter measurements should be recorded in cm and to the nearest multiple of ______________ in CGS system
The Japanese forester Hirata developed a method for deriving the mean stand height through vertical point sampling and the instrument used for the purpose is _________________.
In ______________________, height growth on age shows a typically sigmoid pattern with slow early and late stages and fast growth between.
An observer standing 30 m away from the tree on a level surface and measures the height of the tree with the help of Ravialtimeter and records 15.60 to the top of the tree (top reading) and 1.70 to the bottom of the tree (bottom reading) on 30 m scale. The total height of the trees is ______________.
In the Horizontal point sampling method, a total of 16 partially tallied trees and 10 fully tallied trees were recorded in a sweep of 360$^\circ$ with the help of a Wedge prism. If the calculated basal area per hectare is 72 m$^2$. The Basal Area Factor of the wedge prism is ______________.
In case of girth measurement the basal area of the tree is estimated using the formula
In ______________________, a series of sampling points are selected randomly or systematically distributed over the entire area to be inventoried.
Von Mantel’s formula is best applicable to: ______________
Generally, the relationship between the diameter (d) and girth (G) of tree is given the formula ______________.
