Jungle Transect Observation

Walk a line from the mown edge into the thick stuff, recording at fixed intervals.

The gradient is the finding. Light drops, humidity rises, species change, and all three can be recorded by an eleven year old with simple equipment. Plotting them together shows a pattern that is genuinely ecological.

The page has the transect method, interval recording sheets, and a graphing frame for three variables against distance. It also warns about the practical constraint, which is that the last few metres are usually impassable and the survey has to stop somewhere honest rather than pretending.
