Rat Prevention
Read full descriptionHide full description
To prevent the introduction of rats in Alaska coastal communities, the Tribal Governments of St. Paul and St. George Islands, in cooperation with the USFWS Alaska National Maritime Wildlife Refuge, established a rat prevention program following the construction of commercial harbor facilities on the islands. Regular maintenance and continued improvement of rat prevention stations is extremely important in maintaining effective rat prevention programs. An important component of ongoing prevention efforts and improvements to the system is the ability to track station checks and maintenance actions over time. The Rat Prevention App uses an online database and mobile apps to document rat station monitoring and maintenance in coastal communities of Alaska. The data can be used in a Geographic Information System (GIS) to analyze the effectiveness of defenses and to target areas in need of improvement. The database is shares a common data structure with the BeringWatch Island Sentinel database program conducted by the Aleut Community of St. Paul Island Tribal Government Ecosystem Conservation Office (ECO). For more information or to obtain an account for the Rat Prevention database please contact the Aleut Community of St. Paul Tribal Government at the email address or phone number provided for the app developer.

Udhë connects drivers and passengers who have the same destination. Our focus is to bring carpooling as an alternative to traveling between cities in places like the Balkans and abroad. Udhë offers drivers the ability to post the ride with information like the number of seats, the price per seat, and a meeting point. On the other hand, we offer passengers the possibility to reserve a free seat while reviewing the ride information. Users can chat with each other through the platform chat to coordinate for the ride and after the ride is finished, users can review each other.
