Title
Landslide chronosequence: Tree, site and vegetation factors in the Andrews Experimental Forest, 1981
Abstract
To examine vegetation development on landslides by sampling a chronosequence of landslides 6-28 years old; to determine species that successfully revegetate landslides, and determine whether species composition changes with landslide age.

Enumerated domain for attribute: STOBL

Codes for STOBL
Code Description
2 Marginally stockable: plot unstocked, w/ potential for natural or artificial establishement, but seedling would have poor chance for survival under standard management practices
1 Unstockable plot: unstocked, with natural or artificial seedling establishment & survival unlikely under standard management practices
3 Stocked: plot contained at least 1 established individual seedling of a potentially commercial conifer species
4 Stockable: plot unstocked, but a commercial conifer species seedling could become established naturally, or be established artificially.
