Pinus classification

Whitebark pine (Pinus albicaulis) is a keystone species (Tomback et al. 2001), forming subalpine and treeline forests that supply food and shelter for hundreds of plant and animal species. This trait makes whitebark pine a “quintessential” high elevation conifer and it forms unique habitat types with both geographic and successional variation that support considerable biodiversity across the higher mountains of the United states and Canada. (Tomback et al. 2001, Tomback and Achuff 2010). Whitebark

ponderosa pine forest in the United States. The three-needled Rocky Mountain ponderosa pine (Pinus ponderosa var. scopulorum) is the prevalent form of pine throughout the Colorado Plateau. Gambel oak (Quercus gambelii) is commonly associated with the ponderosa pine at lower elevations as well as the New Mexico locust (Robina neomexicana). At higher elevations it shares habitat with southwestern white pine (Pinus strobiformis), Rocky Mountain white fir (Abies concolor var. concolor), Rocky Mountain Douglas-fir

Mountain Pine Beetle Outbreak: Underlying Cause The Dendroctonus ponderosae (Mountain Pine Beetle) is estimated to have killed 46 million acres of trees from 2000 to 2012 - an area nearly the size of the state of Colorado, as stated in an article released by the Union of Concerned Scientists. In response to this epidemic, the U.S. Forest Service estimates that “as many as 100,000 beetle-killed trees fall to the ground every day in Southern Wyoming and Northern Colorado alone”. The results of the

The Sighing Trees The second of two back doors is white with black accents and a big window in the top half. As you push the door open you hear an array of screeches and clicks. “Don’t let the dog out!” Mother shouts before you walk out the door. Closing itself when you let go of it, the door shuts with a slam. You gently set your foot down onto the step of the small, cement, back porch and your rainboot makes a “thwip” sound. Stepping off of the cement onto decorative stones, triangular and jagged

It was our second day in Montana, and I was so excited to be going on a beautiful hike with my family. The roundtrip was about five miles there and back, and it is one of the most highly rated and enjoyed hikes in Northern Montana. We figured there would be lots of other travelers, and the first part was crowded with people. But as intensity increased, the number of people decreased. We trekked up the steep incline on the first mountain, to the point where we were able to see into the valley far

The paper introduces one of the earliest experimental forests that is also regarded as a forestry research center, the Priest River Experimental Forest (PREF). The forest was established in 1911, lies between the Priest River and the Selkirk Mountains in the State of Idaho. By interpreting its particular existing conditions, including geography, climate, hydrology, soil, vegetation, readers can easily understand its significant role in the region of Northern Rocky Mountain, providing many valuable

Introduction The first question to be addressed in this study is, will there be varying tree seedling species diversity in relation to varying levels of burn severity? My hypothesis for this question is that we will see the highest tree species diversity where we see a moderate level of burn severity. The second question of the study asks, did the presence of salvage logging lead to a difference in the tree seedling densities as compared to unlogged sites? My hypothesis for this question is that

Introduction The objective of this study is to utilize Local indicator of spatial association (LISA), in particular the bivariate local Moran 's I, as a procedure for evaluating the damage of mountain pine beetle infestation over vast lodgepole pine forest with GIS and coarse scale multi temporal Aerial overview survey (AOS) data. The authors point out beetle infestation results in commercial timber loss, increase fire risk, habitat loss. They also point out, a growing concern of spreading beyond

Manuscript for : 696832 Anjelena Cook Pen name: Anjelena Ellett Title: Little Pine Tree's Awakening Little Pine Tree was about three feet tall with bright green needles on all his branches. His favorite color was red. He always wore a thick, red scarf around the trunk of his tree. He was a curious little tree. He noticed the many different colors of the world. (Insert image 1: Little Pine Tree with red scarf standing all alone) He loved the bright blue sky, the fluffy white snow, the

“Somebody call the fire department,” I yelled. "Where is my iPhone?" "I don't know find it!" he replied It all started the second heat waved in a row in the morning as I woke up in the morning, got dressed, brushed my teeth. Heard the sound of my sister yelling at my dog Silky. I walked downstairs to check on what the hustle was all about. In my peripheral vision, I can see my dog chewing on a white golf ball. "Stop chewing on the damn golf ball" she yelled I slowly reached out for the golf ball
