I've been playing around a little bit looking for good site specific weather information for species native locations. Here is one method I have played with. This site can be found at: http://wcatlas.iwmi.org/Default.asp You need to register but it is free and easy. You will need latitude and longitude in degrees, minutes and seconds for your query. Once you do your query you will get a spread sheet like the one below. Just for experimenting I used Dendrobium unicum to research. If you don't have coordinates for a species location there would be several ways to get that info. Here is one way: Go on the Kew site and do a search for a species. Here is the link: http://apps.kew.org/wcsp/[email protected]@291181020130524583 When you do the search you should get a page that includes 3 green tabs. The one on the right is "Further Information". Click on it. On the resulting page is a category "Specimens, distribution and conservation". In that category click on GBIF. On the resulting page click on your species. One of the resulting options is a Google Earth location for a species record. Put your cursor on that location and the Lat/Long will be displayed in the lower right of the Google Earth image. It sounds complicated but it really isn't. Of course you could always buy a Culture Sheet for the species if one is available.
