The Greater Yellowstone Ecosystem: Redefining America`s Wilderness HeritageIn 1872 Congress designated Yellowstone National Park as the world's first national park; nineteen years later, the land adjacent to Yellowstone became America's first national forest reserve. Since that time, the entire Yellowstone region has been the scene of major battles over resource management debates between those who would use the land for extraction of national resources (mining, lumbering, and hunting, for example) and those who believe that

In 1872 Congress designated Yellowstone National Park as the world's first national park; nineteen years later, the land adjacent to Yellowstone became America's first national forest reserve. Since that time, the entire Yellowstone region has been the scene of major battles over resource management--debates between those who would use the land for extraction of national resources (mining, lumbering, and hunting, for example) and those who believe that wildlife and recreation should dominate land use.

 

In this book, experts in science, economics, and law discuss key resource management issues in the greater Yellowstone ecosystem, using them as a starting point to debate the manner in which humans should interact with the environment of this area. Some authors reflect upon the summer 1988 fires at Yellowstone and review the role and effect of fire in the ecosystem. Others offer opinions on appropriate management of elk and bison, key attractions to Yellowstone since its inception. Still others address the question of whether wolves--now a missing component of the Yellowstone ecosystem--should be restored to the region. A final essay by editors Robert B. Keiter and Mark S. Boyce suggests how ecosystem management principles will affect Greater Yellowstone's future and how an ecological process management philosophy might be implemented.

 

This important book, which includes special archival photographs of the Yellowstone area, will be the major source of information on this land for years to come. It is also valuable for all who are interested in how wildlands throughout the world can be preserved in their natural state in the face of accelerating human encroachment.

Lots of extras!
Size: 2+12+12+2 pack
The brushes are a bit flimsier than the original but otherwise fine. I needed it for the rectangular filters more than anything

EUFY 11S
Size: 2+8 pack
Used to replace the ones for my EUFY 11S vacuum. They fit just like the ones and got my vacuum back to cleaning really good. Didn’t realize how loud my vacuum had become until I replaced these parts.

Side brush screw PSA 🤪
Size: Eufy B-18Packs
Reviewing parts for Eufy L60 Review posted for some PSA When you get the brush replacement this kit comes with a tiny screw driver DO NOT USE THAT TINY SCREWDRIVER TO UNDO YOUR SIDE BRUSH IT WILL STRIP THE OEM SCREW AND MAKE IT USELESS. the screw driver included fits the screws that are about 2 mil wide the side brush screw is different. Grab a regular screw driver to undo a side brush. The main rolling brush cover is different but the rubber part still hits the floor at proper height so I don’t see a big issue there. When replacing the filter the filter cover was a little snug but I don’t see a big problem there just be aware to close the cover all the way but be careful not to push too hard so the plastic clips don’t break on the cover. Don’t forget to wipe down all the seals when installing the filter to maintain the seal integrity to keep the suction at top intensity. The dust bags seemed to be cut out with a stencil which gave the cardboard a better appearance than the oem cut out dust bags so that was interesting, dimensions were identical when comparing so I don’t anticipate any issues! Over all I’m glad we have cheaper alternative replacement parts that can be used so thank you! ❤️

Great parts replacement kit for Eufy!
Size: Eufy B-18Packs, Size: Eufy B-18Packs
This kit has made it nice keeping up with our Eufy robot vacuum. All parts were free of defect and fit as it should. Instead of replacing individual piece by piece, I now just change all of the replacement parts at one time and it’s good to go for a while! Great value. Great quality. Will definitely be buying this kit again!
