Pinus jeffreyi, also known as Jeffrey pine, Jeffrey's pine, yellow pine and black pine, is a North American pine tree. It is mainly found in California, but also in the westernmost part of Nevada, southwestern Oregon, and northern Baja California. It is named in honor of its botanist documenter John Jeffrey.
Pinus ponderosa, commonly known as the ponderosa pine, bull pine, blackjack pine, western yellow-pine, or filipinus pine, is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America.
Eldorado National Forest is a U.S. National Forest located in the central Sierra Nevada mountain range, in eastern California.
Plumas National Forest is a 1,146,000-acre (4,640 km2) United States National Forest located at the northern terminus of the Sierra Nevada, in northern California. The Forest was named after its primary watershed, the Rio de las Plumas, or Feather River.
Abert's squirrel or the tassel-eared squirrel is a tree squirrel in the genus Sciurus native to the southern Rocky Mountains from the United States to the northern Sierra Madre Occidental of Mexico, with concentrations found in Arizona, New Mexico, and southwestern Colorado. It is closely associated with, and largely confined to, mature ponderosa pine forests. It is named in honor of the American naturalist John James Abert; nine subspecies are recognised. It is recognizable by its tufted ears, gray color, pale underparts and rufous patch on the lower back. The squirrel feeds on the seeds and cones of the Mexican pinyon and the ponderosa pine when they are available, but will also take fungi, buds, bark, and carrion. Breeding normally occurs in summer, with a spherical nest being built high in the canopy.
The Xyelidae are a comparatively species-poor family of sawflies, comprising about 80 extant species in five genera worldwide, and is the only family in the superfamily Xyeloidea. The fossil record of the family is extensive, comprising more than 120 species and including the oldest fossil Hymenoptera species dating back to the Triassic, between 245 and 208 million years ago. Xyelidae are to be regarded as living fossils since they represent one of the oldest lineages of insects and include still extant forms.
Boggs Mountain Demonstration State Forest is a state forest in Lake County, California that covers the northwest of Boggs Mountain. It was founded in 1949, and came into operation in 1950 when most of the site had been clear cut. The purpose was to demonstrate good practices in restoring and managing a forest. The state forest was open for recreational use, including camping, hiking, mountain biking etc. The 2015 Valley Fire destroyed 80% of the trees. The state forest as of 2021 was replanting saplings.
The pinyon jay is a species of jay, and is the only member of the genus Gymnorhinus. Native to Western North America, the species ranges from central Oregon to northern Baja California, and eastward as far as western Oklahoma, though wanderers are often sighted beyond this range. It is typically found within foothills, especially where pinyon pines occur.
Ponderosa Pine is a census-designated place (CDP) in Bernalillo County, New Mexico, United States. The population was 1,195 at the 2010 census. It is part of the Albuquerque Metropolitan Statistical Area.
The flora of the Colorado Plateau and Canyonlands region is generally characterized by plant adaptations to the arid conditions of the region, and a wide variation of plant communities from wide variations in elevation and soil types. The elevation variation results in temperature variation. Differing soil types are largely due to erosion of different sedimentary layers in the canyons, from the layers at lowest point of canyons of the Colorado River network, to the top layers of the plateau. Exceptions to flora adapted to aridity occur in lowland riparian areas, at springs, and in hanging gardens.
Ponderosa pine forest is a plant association and plant community dominated by ponderosa pine and found in western North America. It is found from the British Columbia to Durango, Mexico. In the south and east, ponderosa pine forest is the climax forest, while in the more northern part of its range, it can transition to Douglas-fir or grand fir, or white fir forests. Understory species depends on location. Fire suppression has led to insect outbreaks in ponderosa pine forests.
In ecology and forestry, yellow pine refers to a number of conifer species that tend to grow in similar plant communities and yield similar strong wood. In the Western United States, yellow pine refers to Jeffrey pine or ponderosa pine. In the Southeastern United States, yellow pine refers to longleaf pine, shortleaf pine, slash pine, or loblolly pine. In the United Kingdom, yellow pine refers to eastern white pine or Scots pine. In New Zealand, it refers to Halocarpus biformis.
Xyela is a genus of sawflies, belonging to the family Xyelidae.
Xyela bakeri is a species of sawfly in the genus Xyela and is endemic to North America. It can be found from Quebec to Florida, and west to British Columbia and California. It has widespread hosts for its larvae, including Pinus elliottii, P. palustris, P. ponderosa, P. sabiniana, and P. virginiana.
Xyela cheloma is a species of sawfly in the genus Xyela that is endemic to North America. It can be found in Idaho, Nevada, British Columbia, Washington, and Oregon. The host for the larvae is Pinus ponderosa.

Xyela gallicaulis is a species of sawfly in the genus Xyela that is endemic to North America. It can be found in Virginia and Georgia. The larva feeds inside shoots and forms galls in its host which include: Pinus echinata, P. elliottii, and P. taeda.
Xyela linsleyi is a species of sawfly in the genus Xyela that is endemic to North America. It can be found in Idaho, British Columbia, Washington, and California. The host for the larvae is Pinus ponderosa.
Xyela lunata is a species of sawfly in the genus Xyela that is endemic to California. The host for the larvae is Pinus coulteri and P. sabiniana.
