- Search for each type of observation using the corresponding tab. You can search for Programs, Plots, Trees, Saplings and Seedlings.
- Any applicable filters can be applied using the left side bar.
- Changing between tabs will keep relevant filters applied. For example, if you are on the Tree tab and have a filter applied for DBH above 20cm, changing to the Sapling tab will keep this filter applied. Then changing to the Plot table would give you plots with Saplings having DBH over 20cm.
- Keep an eye on the SEARCH PARAMETERS box, this will tell you any filters that are being applied to the current tab.
- Each table will give you a sample of the available data. To download the dataset with filters applied, click on the Downloads tab or Download results link.
- Clear all filters and visit the Data Downloads tab to download the entire dataset.
- Below are the fields you can expect to see when you download the NEFIN standardized datasets.
