Analysing Forests Using Dense Point Clouds
2018 International Conference on Image and Vision Computing New Zealand (IVCNZ), 2018A novel method is proposed to acquire tree metrics for forestry managers in New Zealand. This method involves using a UAV to capture images of trees, and then using photogrammetry to generate a 3D model which includes both a mesh and a point cloud. The point cloud is then analysed, and data and metrics are extracted.

Diversity of soil fauna in the canopy and forest floor of a Venezuelan cloud forest
Journal of Tropical Ecology, 1991ABSTRACTArboreal and terresterial soil and lilter were sampled for macro-and microinvertebrates at two locations in a Venezuelan cloud forest. Fauna were most abundant in forest floor soil and associated litter. However, media suspended in the canopy and particularly those trapped in bromeliad shoots were most densely populated, while the diversities ...

Spider Assemblages in Costa Rican Cloud Forests: Effects of Forest Level and Forest Age
Studies on Neotropical Fauna and Environment, 2003We investigated spider assemblages in trees at three cloud forest sites and in trees isolated in pasture habitat in Monteverde, Costa Rica. Spiders were collected from two forest types (primary and secondary) within each forest site, and at two different levels (canopy and understory) within forest types and the pasture.

Clouds and cloud immersion alter photosynthetic light quality in a temperate mountain cloud forest
Botany, 2010Light quantity and quality strongly influence plant ecophysiology, especially in cloud forests. Only a few studies have investigated the quantitative effects of clouds on incident sunlight, and almost no studies have explored the specific effects of cloud immersion on light quality.

The classic question regarding Lyα forest clouds is whether they are confined by the pressure of a hot, diffuse surrounding medium, or by the gravity of dark matter mini-halos. This paper reviews these basic models for forest clouds, considering spherical and slab geometries.
