Data product containing tree heights, survival, and genetic variation for "Genetic Variation in Ponderosa Pine: A 15-year Test of Provenances in the Great Plains"

Datasets Posted on: March 27, 2015
Seeds from 79 natural stands throughout the ponderosa pine range, both east and west of the Continental Divide, were sown and grown in a nursery for three to four years in the 1960's. These seeds were then distributed to plantations, mostly in the Great Plains. This dataset contains the height of the surviving trees after 15 years for 14 plantations.

Data product containing 22-year Nebraska tree heights, survival, and genetic variation for "Ten-Year Performance of Ponderosa Pine Provenances in the Great Plains of North America"

Datasets Posted on: March 27, 2015
Seeds from 79 natural stands throughout the ponderosa pine range, both east and west of the Continental Divide, were sown and grown in a nursery for three to four years in the 1960's. Some of these seeds were then distributed to three different field plantations in Alliance, Hastings, and Plattsmouth Nebraska. These datasets contain individual tree heights of surviving trees, taken at various frequencies from 1968 to 1987.

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.

Data product containing 5-year tree heights, survival, and genetic variation for "Genetic Variation in Great Plains Juniperus"

Datasets Posted on: March 27, 2015
Cones from 275 Juniperus trees were collected throughout the Great Plains from 1973 to 1976 and then sown and grown in a nursery in Nebraska in August of 1977. In 1980 the 2-year old seedlings were distributed to plantations across the Great Plains.

Forest canopy height from Multiangle Imaging SpectroRadiometer (MISR) assessed with high resolution discrete return lidar

Publications Posted on: October 01, 2009
In this study retrievals of forest canopy height were obtained through adjustment of a simple geometricoptical (GO) model against red band surface bidirectional reflectance estimates from NASA's Multiangle Imaging SpectroRadiometer (MISR), mapped to a 250 m grid.

Effects of fall fertilization on morphology and cold hardiness of red pine (Pinus resinosa Ait.) seedlings

Publications Posted on: January 22, 2009
Red pine (Pinus resinosa Ait.) seedlings were topdress-fertilized with granular ammonium nitrate (NH4NO3) at the rate of 0, 11, 22, 44, or 89 kg/ha (0, 10, 20, 40, or 80 lb N/ac) during fall of 2005 in Badoura State Forest Nursery, Akeley, Minnesota. Seedlings received either a single (September 16) or double (September 16 and 23) application of fall fertilizer.

Morphological and physiological evaluations of seedling quality

Publications Posted on: September 29, 2008
Seedling quality and subsequent field performance can be influenced by various stress factors. Measuring seedling quality can help to identify possible crop problems in order to make informed decisions for culturing, lifting, storing, and planting. In addition, seedling quality data can help seedling growers and users to better understand annual patterns among species, stocktypes, seed lots, and cultural treatments.

Juniper seed sources in the Great Plains

Publications Posted on: December 27, 2007
At age 10, 100% of eastern redcedar ( L.) and Rocky Mountain juniper ( Sarg.) trees from several seed sources throughout the Great Plains had survived. Seed sources from southeastern Texas had the poorest survival. Eastern redcedar trees from Kansas seed sources grew tallest, and trees from Montana and southeastern Texas seed sources were the shortest.
