In an attempt to help clarify why we ask for some species to be logged that are not actually potential range-extenders, we've added some categories to each species or sighting to help explain this. In short, we sometimes list non range-extending species to help scientists collect data on species that are otherwise difficult to find. 

 

A brief explanation of each category (or reason for being listed) is here:

 

Potential range extender

The primary aim of Redmap is to track species movements in terms of range extensions – i.e. changes in a species’ distribution range. Global warming has already resulted in many species shifting their geographical range towards cooler environments.

 

Rare/cryptic

Some species can be difficult to study due to their rarity or cryptic nature (i.e. camouflaged). For this reason, scientist may ask Redmap to collect any information possible.

 

Data deficient

A species may me listed as data deficient because there is currently little information on it (i.e. it is poorly studied). This may be in relation to the species, its behaviour, distribution or seasonal movements.

 

Potential range retraction/loss

A species range can also contract or shrink due to changes in their environment. Like range-extensions, this has the potential to impact on the species, the community and the ecosystems involved.

 

Invasive/non-native species

Although the main purpose of Redmap is not to track invasive species, occasionally a scientist will ask for a particular invasive species to be recorded for which it is otherwise difficult to collect information.

 

Conservation value

Data on particular threatened or endangered species is often rare but very important.

 

Other

This category covers a range of reasons why scientists or managers may wish to collect information on a particular species (i.e. particular projects or species they are working on).
