How intensive is the control program? Could be the decrease in body size a result of selection by humans (larger ones might be easier to spot)? Do you have data on the average age of collected animals? Does it decrease too?

The control program right now is very intensive, with 32 staff working in capturing snakes. However, during winter months, efforts decrease as the species enters a type of torpor and it is difficult to see above ground. It cannot be discarded that there is a human selection, but we think it is not the case, although we are just working on that topic. We don’t have age data of all captures but we will have it for all individials captured in 2020, which are about 1500, so we will be able to check for that later on. Thank you very much for your questions!!!!
