Keystone species are those whose presence and role in an ecosystem is paramount to the point that they have a disproportionate effect on other organisms within the system. Ironically, though they have a lasting effect on the ecosystem, they are the least in count.
Who knew...they all matter!
Thank you for visiting.
He's even cuter in Large!
means it has a larger influence on its environment than its abundance. It plays key role in maintaining the population of other animals in an ecological community.

A sweet-looking pair of CSX SD40-2s descend the West Slope of Sand Patch Grade on a fine Winter afternoon.
East Beckwith Mountain provides the backdrop in this view across an active beaver pond ringed with aspen in their brilliant fall colors. American beaver (Castor canadensis) are probably the best example of what ecologists call “keystone engineers,” a term used to describe an organism that impacts its environment disproportionately relative to its abundance. In other words, there aren’t a lot of beavers, but those few beavers have a huge impact on the landscape through their construction of dams. These dams alter the shape of valleys, increase the amount of standing water, and impact the abundance plants (such as the aspen) and animals that rely on greater water availability. The beaver dam and lodge for this pond are out of view to the right.
East Beckwith Mountain is part of the West Elk Range, formed principally by volcanic intrusions into sedimentary rock. A bit of fresh snow is visible on the north slopes, hinting that the beautiful fall weather and colors will soon be over.
Keystone Dam is located on the Arkansas River near Sand Springs, Oklahoma. Keystone Lake, above the dam is fed by the Arkansas River and the Cimarron River. Started in 1956 and completed in 1964, it provides electrical power and flood control for the Tulsa area.
A quick run from Otis got them over to Pine Yard for work with no time to squeeze out another shot. Getting their train back together and departing, there was only one more place I needed to get the PRR with the last of the late day light. I did, but barely -- just as the Arcelor Security guy said it was time to leave! The mills of East Chicago, Indiana.
The Norfolk Southern business train runs left-handed on the former N&W Pocahontas Division mainline. The immaculate covered wagons started the morning in Norfolk, Virginia and will tie up for the day in a few hours at the division point of Williamson, West Virginia. The Coca-Cola lettered building is just one of the many landmarks on the famed Elkhorn Grade in McDowell County West Virginia.

A BN-painted SD70MAC leads a newer BNSF unit on empty oil train K055, headed west down the western slope of Sand Patch grade at Keystone.
Light sleet falls on a chilly December afternoon as the Pennsylvania Railroad heritage unit pulls Norfolk Southern train 21M through downtown Harrisburg.
As daylight begins to filter through the fog, an NS coal train rumbles through Keystone, WV, assisted by the Lehigh Valley heritage unit on the rear.
Deep gorge near Valdez Alaska, cut in the slate rock by the Lowe River.
In 2014 heavy snow (typical of the area) and avalanches completely filled this gorge in minutes, luckily no one was on the road at the time. The Lowe River was also blocked, and a new term was coined for the lake that flooded upriver from the 1500 foot long x 100 foot deep avalanche... a 'Damalanche.'
Dash 9 #9275 is in charge of an empty grainer heading west along the Pokey in Keystone, WV. 9275 has since been rebuilt into AC44C6M #4557 in February of 2022.

For the first time in nearly ten years, the iconic PRR 'keystone' logo adorns the nose of Pennsylvania Railroad E8 5898. Used by the St. Louis, Iron Mountain & Southern as power for their excursion trains, this locomotive has spent most of the last decade cycling through phases of bodywork and partial repaints. With the reappearance of the nose logo in autumn 2022, the 5898 looks the most 'complete' it has in a long time.
Except during winter, StLIM&S operates excursions most Saturdays of the year. Here we see the train rolling across a small and mostly weed-obscured trestle south of Jackson, MO on October 29, 2022.
