Yes, I know of quite e list of libre sources, only some of which are digitised and online. So (continuously) exporting data from the hundreds of small observation or collection databases or going our and scanning the old offline materials would be what you could organize with better software.

There are also ways to increase the collection of libre data. You could auto-generate field trips for holiday makers or school trips. Give them an auto-generated itinerary leading them past places with flowers, insects or birds with a list of things they should look out for and photograph or determine with keys. Make it into a game like geocaching or a treasure hunt. You generate it based on individual tastes (walking, bicycle, car tour, camper, bustour), individual or group size, age and knowledge level, temperature, season, time of day, climate, location, etc.
