From a B.C. perspective and North American perspective, does this not duplicate the efforts of other databases? E-Bird is a North American database that hundreds of birders contribute to and has become increasingly popular. This tool can be used to track bird populations and does have potential to work towards conservation. In B.C., rare plant sightings should be submitted to the Conservation Data Center (along with other sightings of other provincially-listed species). E-Fauna and E-Flora are tremendous efforts and they are an invaluable resource to B.C. naturalists - these two projects have had an amazing showing of support and hopefully people help build the image databases and, if exact location coordinates are taken, contribute to our understanding of the distributions of species in B.C.
In summary, I don't think your site is a bad idea and not worthy of attention, but I think the niche has already been filled at least on the provincial level. If more sites like yours are started, it could dilute the efforts of other databases working towards the same goal.
