Mean daily sapflux density (cm/hr) by sensor at each of four study sites. Each sensor represents flow within the xylem of a sample ‘ōhi’a tree. Daily volumetric soil moisture (m^3/m^3) is also given. The number of erroneous or blank values and the standard deviation are given for each sensor, each day. All sensor outputs are given, including erroneous values.
Throughout the world, forests cover mountain slopes only up at a certain elevation. Above that level, trees become scattered. Higher up, no trees are found. The level where the forest ends, called the forest line or timberline, is higher in tropical areas than in colder regions, suggesting that cold climate conditions prevent forests from growing at higher elevations. On tropical island mountains, such as those in the Hawaiian Islands, the forest line is found at a lower elevation than we would expect based on the temperature. This leads us to suspect that some factor other than temperature, such as low rainfall, might be controlling the level of forest lines on these tropical islands. In this project, we sought...
