Your presentation explicitly addresses the importance of snakebite victims its consequences very well.
I also have seen a LINE group which has been created by a volunteer group of people (Hotline LINE Snake in the house; สายด่วนงูเข้าบ้าน) 
They can identify type of snakes by sending them a picture and they will usually respond within 5-10 minutes. It is also a good opportunity to work with this group owner if possible (just the idea), so that if there is any venomous snake reported – they might be able to provide you a location from where the snake is being spotted and then alert a surveillance system to warn people in the nearby area to become aware.
Your presentation also provides detail on how to collect data as a measurement for quality domains! Very useful.
