Not directly related to data, more to postings. But as a frequent poster who does it for phenological reasons, hoping to be part of many more observers to give the data validity, I have been contacted by researchers to monitor specific species and in one case requested to get a speciman for a herbarium. Although my photo conditions restrict only commercial use of my photographs, I have been contacted by educational and public institutions to use some of my photos or authors who wish to include them in their articles. I was able to inform the invasive plants coordinator of a distict in SW Alberta where there is a provincial Invasive Weed Council about checking on posts within their area of jurisdiction to determine when particular species on their watch list might be occurring in their area. Just to test it, I posted spotted knapweed along a lake. Two weeks later, I visited that same lake – the knapweed patch was no longer there. (Since you don’t make evaluations on invasiveness, I’m not sure it would meet your positive standard). It would seem that for those people who contacted me, having this source which seems to have helped them, would make the site a plus.
On my part, with no coursework in science at the collegial level, the information under each species often does not give adequate ecosystem information, nor when it comes to species which undergo metamorphic changes, only scant note of each life stage without describing the conditions nor the variations in changing status. I’ve found, for instance, alligatorweed flea beetle larvae in hollow stems, but more frequently in envelopes of top-of the-plant leaves sealed with silk. One independent source notes that this latter situation occurs on alligatorweeds which grow on land near water, but tubular larval housing more common on those in water. My observations are almost all on water or next to water. Yes, there are citations, but having more depth in the text would be much more helpful and would help in learning much more about the observed species. I would hope that those familiar with this beetle in its home territory might be better able to contribute to furthering information (in the US it was introduced in the 80’s as a biocontrol agent.) Wouldn’t that be a real collaboration internationally?
