Title
Pinon-Juniper Plant Dimension Study at the Sevilleta National Wildlife Refuge, New Mexico: 1989-1999
Date
1993
Abstract
This project was designed to investigate the response of plant growth and reproduction to short- and long-term variation in biotic and abiotic environmental variables. Several perennial taxa, including tree (Juniperus monsperma and Pinus edulis), shrub (Larrea tridentata) and bunch grasses (Oryzopsis hymenoides (now Achnaterum hymenoides) and Sporobolus contractus) species, were monitored at 1-3 sites differing in elevation and topography as well as edaphic variables and annual precipitation. The sites represented optimal or marginal/transitional zones for particular species. Demographic measurements were made biannually, after the 'wet' (fall) and 'dry' (spring) seasons. For tree and shrub species, estimates of growth and reproduction were based on branch demography, with ten branch tips from 10-20 individuals per species per site repeatedly measured from 1989-1993. For J. monsperma, P. edulis and L. tridentata, vegetative growth (i.e., branch growth) as well as reproduction were monitored. Additional measurements included needle length for P. edulis and leaf production, leaf size and branchlet production for L. tridentata. For grasses, basal diameter, leaf length and reproduction were monitored for 100 individuals per species per site.Pinon-juniper plant dimension data was collected to obtain a measure of the change in the size of individual pinon and juniper trees through time. This data encompasses growth over 11 years and was to be used in conjunction with data in the Sevilleta plant demography and plant physiology data bases. However, those studies were discontinued in 1993. This project, SEV025, contains only data on pinon-juniper plant dimensions. Data on other variables and species is contained in SEV006, SEV024, SEV026, SEV027, and SEV028.

Spatial coverage
Location: Sepultura Canyon is one of the largest ravines coming down from the Los Pinos Mountains to McKenzie Flats. Originally a core site, rodent webs and vegetation line-intersept transects were located in Sepultura Canyon through 1992, when the US Fish and Wildlife Service established the Sevilleta Wolf Management Facility in the area.Vegetation: Vegetation is characterized as juniper-savanna with arroyo-riparian species., siteid: 5
