MANHATTAN, Kan. — A Kansas Forest Service official says streamside forests and woodlands have improved during the course of a six-year, $1.8 million project, but work remains to ensure the viability of local water resources.
Robert Atchison, coordinator of the rural forestry program at KFS, said the agency has administered the grant from the Regional Conservation Partnership Program (RCPP) to focus on water quality conservation forestry practices on more than 14,296 acres in Kansas.
“The project focused on water quality and quantity resource concerns associated with the loss of riparian forests and streambank erosion, which contributes to the sedimentation and nutrient loading of federal reservoirs,” Atchison said.
RCPP is a grant program of the Natural Resources Conservation Service that coordinates activities to address on-farm, watershed and regional natural resource concerns.
Atchison said federal reservoirs in Kansas are losing water storage capacity to sedimentation – some have lost more than 40%. Nutrient loading from runoff into streams and rivers that feed the reservoirs are causing frequent algal blooms that can be harmful to humans and animals.
These reservoirs provide water in some manner for two-thirds of the state’s population.
“Healthy, functioning riparian forests are an integral piece in improving the quantity and quality of water in Kansas reservoirs,” Atchison said. “Our foresters worked with landowners to conduct more than 5,000 acres of forest stand improvement during the grant, ensuring the long-term function of the forests.”
The forests intercept rainfall in their canopy, reducing the amount of rain that reaches the ground. When rainfall reaches the ground, the trees take up water from the soil through their roots, increasing soil water storage and reducing runoff.
Atchison said forests’ contribution of organic matter also increases water storage in the soil. Forested watersheds produce less runoff, reducing downstream flooding that can erode streambanks, damage property and destroy habitat.
The 125 acres of riparian forest buffers that were planted will provide long-term bank stabilization benefits as well as increase wildlife and aquatic habitat.
Atchison said additional grants provided $2.3 million in technical assistance that were used to hire additional foresters to serve Kansans. The RCPP grant also generated more than $12 million in contributions by partner agencies.
The Kansas Forest Service used $273,000 in grant funds to help focus outreach and conduct Stream Visual Assessment Protocol (SVAP). The Kansas Alliance of Wetland Streams (KAWS) led the work to conduct a forest inventory, riparian forest assessments and GIS classification of functioning stream condition in 10 priority watersheds. This information will guide future work, according to Atchison.
He added the project brought significant attention to the important role riparian forests play in stabilizing streambanks and reducing sediment loads. However, the grant had it challenges, and barriers still need to be overcome to restore and protect riparian forests.
“While we’ve made great progress with our many partners, we still face challenges with the high cost of bank stabilization, inadequate financial incentives to engage landowners, and the hesitation to give up cropland for riparian forest buffers,” Atchison said. “All of this needs to be addressed for the work to continue, along with state funding support for water quality forester positions.”
