Supplementary v’s Collocated installations

 All supplementary traps will likely be converted to collocated traps in the future as this allows for more flexibility, so we recommend people create collocated traps, rather than supplementary traps.

A supplementary installation is an additional installation that is part of the same physical set as another installation. It is most commonly used for double-trap sets - for example, if you are installing a tunnel with two DOC 200 traps inside it. In this case you would add a trap as normal (recording the type, line, location, etc). And then you would add a supplementary trap of the same type to it.  You can then record data (trap checks and catches) separately for each side of the trap.  However, the two traps remain tied together, and the information, such as line, location, etc, remains the same for both.

When you add a trap via the website, you can specify that it is a double trap, and this will automatically create a supplementary trap of the same type.  It will have the same code with the text "supplementary" appended to it.

Another example is a rat tunnel with a mousetrap included in it.   You can add the mousetrap as a supplementary trap, and it will remain linked to that set.

Supplementary installations can not be retired or moved independently. if you want to move one, you must retire them both and reinstate them in the project independently. this will mean the new installations will not have the records with them, but in the retired installations.

Note: you can't add supplementary traps via the App, but you can add "collocated traps."

Collocated installations are installations located in the same place, but still remain independent of the installation with which it is situated.

for example:

a trap and a monitoring site at the same location

a double-set trap

traps for different species in one spot.

A bait station

A monitoring station

Same place means having exactly the same coordinates (longitude, latitude.)

A collocated installation can be retired, moved and coded independently from the original installation.
