Revegetation Of Disturbed Semiarid Grassland In Canyonlands National Park, Susan B. Goldberg Jan 1993

Revegetation Of Disturbed Semiarid Grassland In Canyonlands National Park, Susan B. Goldberg

Canyonlands Research Bibliography

A grassland restoration project was conducted in Canyonlands National Park on an area recently disturbed due to construction. Two native grasses (Oryzopsis hymenoides and Stipa comata) were seeded with 18 different soil treatments. Stipa density and relative mycorrhizal colonization were measured. None of the soil treatments resulted in significantly greater Stipa density than the control treatment of seeding only plus water. There was very little correlation between Stipa density and mycorrhizal colonization based on the treatments (r2= 0.011 p = 0.05). Three treatments produced 3 to 5 times the VAN colonization as the control including spring cryptobiotic soil crusts, with …

Data Sets

The Bay Study Group was created by the City of Tampa in 1976 to monitor the effects of pollution abatement that occurred in Hillsborough Bay when the city’s wastewater treatment plant was upgraded from primary to advanced treatment in 1979. The Bay Study Group documented a remarkable restoration of water quality parameters and biological indicators in Hillsborough Bay from the mid 1980s until 2009, when it was disbanded. This zip Geodatabase file contains the photo point locations, aerial photos, and flight maps for the year 1993.
