Estimating Soil Seed Bank Characteristics in Ponderosa Pine Forests Using Vegetation and Forest-Floor Data
Estimating Soil Seed Bank Characteristics in Ponderosa Pine Forests Using United States Department of Agriculture Vegetation and Forest-Floor Data Forest Service Rocky Mountain Research Station Research Note Scott R. Abella and Judith D. Springer RMRS-RN-35 September 2008 Abstract—Soil seed banks are important for vegetation management because they contain propagules of species that may be considered desirable or undesirable for site colonization after management and disturbance events. Knowledge of seed bank size and composition before planning management activities facilitates proactive management by providing early alerts of exotic species presence and of abilities of seed banks to promote colonization by desirable species. We developed models in ponderosa pine (Pinus ponderosa) forests in northern Arizona to estimate the size and richness of mineral soil seed banks using readily observable vegetation and forest- floor characteristics. Regression models using three or fewer predictors explained 41 to 59 percent of the variance in 0- to 2-inch (0- to 5-cm) seed densities of total and native perennial seed banks. Key predictors included aboveground plant species richness/10.8 ft2 (1 m2), litter weight and thickness, and tree canopy type (open or closed). Both total and native perennial seed banks were larger and richer in plots containing: (1) species-rich understories, (2) sparse litter, and (3) tree canopy openings. A regression tree model estimated that seed bank density of native perennials is 14-fold greater if aboveground plant richness exceeds eight species/10.8 ft2, forest-floor leaf litter is < 1 inch (2.5 cm) thick, and tree canopies are open. Introduction Soil seed banks are important for vegetation man- agement in ponderosa pine forests in at least four ways. -
BLM Seeds of Success Program
collect • evaluate • establish • grow • store • restore Seeds of Success (SOS) was established in 2001 by the Bureau of Land Management (BLM) in partnership with the Millennium Seed Bank Project (MSB) to collect, conserve, and develop native plant materials for restoration across the United States. The initial partnership between BLM and MSB quickly grew to include many additional partners, such as botanic gardens, arboreta, zoos, and municipalities. These SOS teams share a common protocol to coordinate seed collecting and species targeting efforts. SOS is a vital part of the Native Plant Materials Development Program. To date, SOS has over 12,000 native seed collections in its National Collection. This material is used for restoration projects, native plant materials development projects such as germination trials, common garden studies, and protocol establishment. Portions of each collection are also held in long-term storage facilities for conservation. 2010 was an especially productive collection year, made possible by an influx of $1.25 million in American Recovery and Reinvestment Act funds. These funds put an additional 43 collectors on the ground, allowing SOS to nearly double collection capacity. 3,000 ~2,700 SOS has partnerships nationwide for permits to collect on 40 USDA Forest Service National Forests, 10 U.S. Fish & 2,500 Wildlife Service National Wildlife Refuges, 6 Department 2,000 of Defense areas, The Nature Conservancy’s lands and 1,474 1,504 1,500 multiple state and local lands. Non-federal SOS partners 1,235 1,208 1,012 1,044 1,058 have made significant collections in the Midwest, Texas, 1,000 685 447 Eastern U.S., and San Diego County. -
