Seed and ring width data from 'Climate drivers of seed production in Picea engelmannii and response to warming temperatures in the southern Rocky Mountains'

Datasets Posted on: June 08, 2016
Seed production by Picea engelmannii was monitored at 13 plots distributed across an approximately 670 meter elevation gradient in the Fraser Experimental Forest near Fraser, Colorado. Seeds were collected annually between 1970 and 2010 from ten wire mesh seed traps located in each of the 13 plots. Annual plot level estimates of seed abundance were derived from an average value of the 10 traps.

Data product containing nest site selection and survival data for "Nesting ecology of greater sage-grouse Centrocercus urophasianus at the eastern edge of their historic distribution"

Datasets Posted on: August 27, 2015
The greater sage-grouse (Centrocercus urophasianus) in North Dakota is listed as a Priority Level 1 Species of Special Concern by the the North Dakota Game and Fish Department due to the declining populations between 1965 and 2003. This data publication contains nest site selection and nest survival data for the greater sage-grouse in North Dakota between 2005 and 2006.

Capture history and handling times for "Netguns: a technique for capturing Black-backed Woodpeckers"

Datasets Posted on: August 27, 2015
This data publication includes capture history and handling times for Black-backed Woodpeckers (Picoides articus) between September 2008 and June 2011 in the Black Hills of South Dakota. Study sites chosen were forests impacted recently by fire or mountian pine beetle infestations. Seventy-five Black-backed Woodpeckers were captured using Coda or carbon dioxide powered netguns, and 26 of those birds were recaptured.

Data product containing 20-year tree heights, diameters, and genetic variation for "Scots Pine in Eastern Nebraska: A Provenance Study"

Datasets Posted on: March 27, 2015
Seedling progenies of 36 rangewide provenances of Scots Pine (Pinus sylvetris) were established in a field test at Horning State Farm experimental area near Plattsmouth, Nebraska in April of 1962. Tree heights were measured at the end of each growing season from 1963 through 1969, and again in 1971. Tree height and diameter at breast height were both measured at the end of the growing season in 1976, 1978, 1979, and 1981.

Data product containing 16-year tree heights, survival, and genetic variation for "Genetic Variation in Blue Spruce: A Test of Populations in Nebraska"

Datasets Posted on: March 27, 2015
In the fall of 1969 seeds were collected from more than 400 trees throughout the natural range of blue spruce (Wyoming, Utah, Colorado, Arizona, and New Mexico). These seeds were sown in a nursery in Michigan in 1970. In 1973 over 800 of those seedlings were planted in a plantation in Horning, Nebraska. This dataset contains annual tree heights of surviving trees from 1973 to 1988.
