Subject: [Tweeters] eBird Hotspot Boosting

From: J Christian Kessler - 1northraven at gmail.com

this is to misunderstand the role of hotspots and their use in science.
scientists are looking at species over much wider areas than just one or a
few hotspots. in this context hotspots are non-random sampling points.
any scientific statement about a species population (occurrence; density)
for an area would have to take into account the density of hotspots in that
area, the frequency of reports on each hotspot, along with other habitat &
and such variables.

hotspots are themselves highly non-random and hence non-scientific. some
hotspots cover definable areas (like the UBNA) that may include multiple
discrete habitats, while others are simply geographic coordinates for a
place birders have found productive. there is from a scientific
perspective no rhyme or reason to the identification of hotspots as
individual locations, but as a collective set of data points covering a
separately identified (by a scientist researching a specific question)
area, they provide a time-series and wide-area picture of great value.

and a key element of that value is the occurrence of a species by season.
eBird bar charts are organized for occurrence by week of the year. in the
end, "flooding" a hotspot only makes inherently non-random data even less
non-random, which is to say statistically biased in hard to determine
ways. starting a new hotspot in an area with few of them could, on the
other hand, be beneficial to the comprehensive data set.
