A description of major programs and sample outputs follow: 



1. Leaf Area Index (Table EI). The data collected by use of the 

 point frame are edited and analyzed to determine the leaf and 

 stem area by species and total foliage by specific sites and 

 times during the growing season. The point frame consists of a 

 support through which a number of pins (usually 39) can be passed 

 at any set inclination (normally 32.5°). The data for each con- 

 tact are pin number, distance from pin contact to top of frame, 

 species contacted, live or dead, leaf, stem or flowering struc- 

 ture. The program produces listings and summarized by quad, plot, 

 and site, subdivided by species and later summarized to give 

 total foliage, the output information being the calculated leaf 

 area index, for each of 9 height ranges. 



2. Primary Production and Chlorophyll Analysis (Table EII) . Des- 

 tructive sampling of standing foliage in quadrats of specified 

 size permitted laboratory analysis of plant material throughout 

 the season, commencing with harvest of standing dead material 

 before the current year's production had begun, and ending after 

 frost at the end of the season. These samples were weighed and 

 analyzed for chlorophyll content at Barrow. These data were then
