Hi Arjun, I hope you are well.

The type of sampling depends on the purpose of sampling. There is no better or worse for sampling method (any type of sampling), although there are guidelines that you could follow, i.e. you can adapt and / or improve the existing methods to answer your research questions. Here I give some links to archives that could help you to choose the best methods for your sampling. I hope you will find them useful.

Best regards

Cristian Martínez

It will depend on the main object. For instance; to make a survey, you should walk and collect or record every plant species, trying to include a large area as possible; to make a community assessment I recommend you Braun Blanket ´methods. No matter the method, the point is to record all the information as possible for that other people, when read your information, can obtain the real information of the studied area.
