Flora Health
Averaged across 5 sites: all physiological indicators within normal operating range. Trees are photosynthesising, growing, and transpiring as expected for this time of year.
Sap Flow Rate0.79 g·m⁻²·s⁻¹normal
Sap flow at 49th percentile — within normal operating range
Stem Growth Rate2.9 µm/daynormal
Radial growth at 37th percentile — normal cambial activity
Tree Hydration76% RWCnormal
Hydration adequate — trees fully recharging overnight
Stomatal Openness0.85 index (0–1)normal
Stomata open — photosynthetic gas exchange operating normally
Water Use Efficiency0.94 relativenormal
Normal WUE — carbon uptake and water use in balance
Narrative context
Trees are actively photosynthesising with open stomata (0.85) and healthy sap flow (0.79 g·m⁻²·s⁻¹). Stem growth is averaging 2.9 µm/day — consistent with the seasonal baseline.
Averaged across 5 monitored sites over 7 days. Tree response metrics derived from sap flow, dendrometer, and soil-plant-atmosphere modelling. Baselines: 2019–2024 seasonal climatology.

High bat activity near Simpson Falls
Bat detector recorded 28 passes/hour between 19:00–21:00, with an estimated 4 species. Activity is above the seasonal baseline of 18 passes/hour — likely driven by warm, calm conditions favouring insect emergence.
