A Gis-Based Habitat Model Predicting Elk Nutritional Condition in the Pacific Northwest
… linking the biomass of suitable elk forage (BSF) and dietary digestibility (DD) to model habitat quality for elk at 3 sites in the PNW: 1 in western Oregon (Wendling), 1 in southwestern Washington (Pe Ell), and 1 in northwestern Washington (Nooksack). BSF was best predicted by overstory …

Modification of a biosand filter in the northern region of Ghana
Four local plastic design (LPD) BSFs were constructed in Northern Region, Ghana, to test and evaluate an experimental modification of the LPD BSF for treatment of highly turbid water. Modifications of the LPD BSFs were made in order to provide an additional "biolayer," the core layer of a BSF where …
