“A new study on the threatened grasshopper sparrow in New Jersey demonstrates that farmland conservation programs can potentially play an important role in reducing the extinction risk of grassland birds.” From Conservation Maven.
Lee et al. (2009) examined the impact of fall and spring harvests on biomass yield in switchgrass and other potential bioenergy grasses. There was little drop-off in biomass yield in spring harvests compared to fall for switchgrass, and big bluestem actually produced slightly more in spring. This is great news for wildlife conservation. Spring biomass harvests would preserve valuable winter cover for birds and other critters, and more closely mimic natural disturbance regimes. And, still provide a profitable biofuel crop. Now that’s what we mean by practical conservation
If expiring CRP is not re-enrolled, consider haying instead of other uses – better for erosion and wildlife than plowing and planting (from Plant Management Network).
USDA FSA has a map of the Primary Nesting Season (PNS). PNS is the period of high nesting activity of grassland birds, and managed haying and grazing is prohibited during this time frame. Notice how much the dates and length of the PNS varies even among adjacent states.
The USDA just opened up > 24 million acres of CRP to help offset increased feed costs. Many wildlife concerns are directly addressed. “Eligible land may not be hayed or grazed until after the end of the primary nesting season. Also, some ….. land must be reserved for wildlife and …… must have a conservation plan. In many instances, the removal of some of the grass cover will increase the diversity of the stand and provide long-term benefits for wildlife. Further, the most environmentally-sensitive land …. will not be eligible.” {emphasis mine}. This has been met with mixed reviews, so I link some of them below:
