Selection of Planting Sites

At first the selection of the planting sites was left entirely to the

judgment of the cooperators, and most of them assumed that the Asiatic

chestnuts have site requirements similar to those of the native American

chestnut. Because the American chestnut often occurs on dry ridges and

upper slopes, especially where soil is thin and rock outcrops are

frequent, the cooperators proceeded to plant the Asiatic chestnuts on

similar "tough" sites. They believed that the planting of forest-tree

species is justified only on defrosted areas that have reverted to

grassland, or worn-out, unproductive agricultural land, or on

wastelands--sites that we now know are better suited to the growing of

conifers rather than hardwoods. As a result of this unfortunate choice

of site selection, together with the several severe drought periods

recurring in the early thirties, the cooperators lost most of their

trees during the first and second years after planting.

Inspections of some of these planted areas after a lapse of from 10 to

15 years indicated that the sites still support only a scant herbaceous

cover, with broomsedge and povertygrass predominating, and with no

evidence of native woody species encroaching on the areas. The few

surviving Asiatic chestnut seedlings were sickly looking, multi-stemmed,

misshapen trees, heavily infected with twig blight and chestnut blight,

and severely damaged by winter injury. But despite these heavy losses, a

few plantations succeeded at least in part, and from these limited

areas, together with an appraisal of the situations where some of the

earlier planted chestnuts grew well, valuable information as to the site

requirements of the Asiatic chestnut species was obtained.
