R.A. Diaz-Varela et al. 2010. Assessment of conservation status in managed chestnut forest<br />

203<br />

behaviour of predictors <strong>and</strong> chestnut forest quality classes. Focusing on high quality st<strong>and</strong>s, they<br />

occur mainly on quite steep slopes <strong>and</strong> also tend to occur at altitudes higher than 600 m showing<br />

a relative low textured <strong>and</strong> low greenness value. This is consistent with the theoretical<br />

confinement of the chestnut traditional forest to mountain or marginal areas, where agricultural<br />

activity is constrained by the environment, <strong>and</strong> also indicates that a relative low degree of<br />

heterogeneity in the patches might be used as an indicator of well preserved st<strong>and</strong>s. Good<br />

quality st<strong>and</strong>s can also occur on more textured (heterogeneous) patches, but in this case<br />

corresponding to small plots, fact that could be interpreted as the separation between large<br />

heterogeneous forest patches with lower relative chestnut coverage <strong>and</strong> small plots dominated<br />

by chestnut but with some heterogeneity in the st<strong>and</strong> characteristics.<br />
