Camera trapping. Snapshot Serengeti. Camera Traps for Research. 3. Infrared vs. Incandescent. This is an age old debate. The risk of scaring animals with an incandescent flash, but the reward of having a color night photo. Incandescent flash camera traps are almost required for cat researchers because they must be able to identify individual animals based on their spots. The infrared cameras will be less "intrusive" to normal wildlife activities as they will not spook the animals when taking a picture in the black of night. Also, if the camera is going to need to be completely "covert" at night, you will need a No Glow Infrared Camera Trap.

Remote tending. Home> Traps>Trap-Alert™ Trap-Alert™ Remote Trap Management is a combination of hardware, software, GPS and wireless technologies that enables users to actively monitor the status and location of traps through a web-based application, which significantly increases the efficiency of managing large numbers of traps. Inexpensive sensor kits allow you to easily retrofit your existing traps in advance, making them Trap-Alert™ ready and allowing your traps and devices to be changed out on the job by simply unplugging one device and replacing it with another.

When a trap is triggered the wireless technology of Trap-Alert™ updates the status of the trap on the Trap-Alert™ website. On that website you can see each trap that is attached to a module. The website will tell you the trap that has been tripped, and using GPS technology, will show you where that trap is located on a map. Trap-Alert™ makes efficient use of its rechargeable battery to ensure a 45-60 day run-time per charge.

Fencing and Pastures. Wolf/livestock conflict mgmt. MN deer-exclusion fencing. MN Fence Specification. Montana Fish & Wildlife. Beaver Solutions. Most people only become aware of beavers when they are a nuisance, but did you know that biologists classify beavers as a Keystone species? Beaver ponds create wetlands which are among the most biologically productive ecosystems in the world1. They increase plant, bird2 and wildlife variety3, improve water quality4, and raise salmon and trout populations5. This one species supports hundreds. How is this possible? By opening the tree canopy, sunlight reaches the water and triggers an explosion of biological activity.

Algae and aquatic plants grow in the sun drenched, nutrient rich water. While infamous for killing trees, beaver dams actually create diverse habitats. Beaver ponds become magnets for a rich variety of wildlife. How do dams affect water quality? Beaver ponds also recharge our drinking water aquifers, stabilize the water table, and better maintain stream flows during droughts. U.S. Beavers & Flow Devices. 1.) Effectiveness of Water-flow Devices as Beaver Conflict Resolution Tools (summary - for a full transcript contact us). 2.)

Two Break-through University Beaver Reports, Flow Devices Solve Flooding Problems in Two States. 3.) 4.) 5.) 6.) 7.) 1.) By Mary Spock 2006. Management of beaver-human conflicts causes much controversy in the Commonwealth of Massachusetts, as does the related law, the Wildlife Protection Act. Focuses only on professionally installed devices, as the variation in self-installed devices, both in design and in effectiveness, is too great to yield meaningful answers;was conducted by a party not affiliated in any way with any of the installers of the surveyed devices;shows that people who use the devices are satisfied with them, but also finds an undercurrent of skepticism about them. A telephone survey of clients found that 93.3% were satisfied with the devices, and 63.3% of respondents claimed the highest level of satisfaction offered as a response, "very satisfied.

" Flow device (Wikipedia) Trapezoidal protective fence installed after re-opening dammed culvert Flow devices are man-made solutions to beaver-related flooding problems. Traditional solutions have been focused on the trapping and removal of all the beavers in an area. Benefits of beavers[edit] River otter standing on beaver pond flow device in urban Alhambra Creek Re-opening beaver dam to install pipe leveler to regulate height of beaver pond in downtown Martinez, California Beavers faced near extinction from unregulated trapping across North America during the early to mid-nineteenth century. The most common beaver-related flooding issues that people encounter are caused by blocked road culverts or freestanding beaver dams. History of flow device solutions to beaver dams[edit] Contemporary flow devices[edit] Before: Culvert fence and pond leveler pipe system installed with beaver pond drained After: Culvert fence and pond leveler pipe after beaver re-build their dam Beaver dam pipes[edit] Culvert protection[edit]
