Biomass production and potential water stress increase with planting density in four highly productive clonal Eucalyptus genotypes

Publications Posted on: March 11, 2017
The choice of planting density and tree genotype are basic decisions when establishing a forest stand. Understanding the interaction between planting density and genotype, and their relationship with biomass production and potential water stress, is crucial as forest managers are faced with a changing climate. However, few studies have investigated this relationship, especially in areas with highly productive forests.

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 nursery management in Chile

Publications Posted on: November 06, 2008
The forest economy in Chile is based on products from artificial reforestation efforts on approximately 2 million ha. From these, about 1.5 million ha (75%) are planted with Pinus radiata, 400,000 ha (20%) with species of Eucalyptus, principally E. globulus and E.
