High-altitude Habitat Assessment & Sustained Systems Laboratory
The HHASSL monitoring network spans 12,400 hectares of old-growth temperate rainforest, tracking the complex interplay between canopy dynamics, soil mycorrhizal networks, and atmospheric carbon flux. Our sensor array captures data at 15-second intervals across 847 distributed nodes, feeding into the real-time visualization systems displayed throughout this interface.
Each data point represents a living measurement -- respiration rates, moisture gradients, fungal network conductivity -- drawn from instruments embedded within the forest substrate itself. The research station has operated continuously since 1994, accumulating one of the longest unbroken ecological datasets in the Pacific Northwest region.
Beneath the forest floor lies an intricate web of mycorrhizal fungi -- the "wood wide web" -- connecting trees across vast distances. HHASSL sensors track nutrient transfer rates, signal propagation speeds, and network topology changes in real time. The visualization below represents a snapshot of the current network state, with each node corresponding to a monitored junction point.
Recent analysis reveals that network conductivity peaks during pre-dawn hours, suggesting a circadian rhythm in fungal nutrient transport that mirrors the photosynthetic cycles of the host trees above. Node clusters with the highest connectivity tend to center on the oldest specimens in the forest -- trees exceeding 400 years serve as primary hubs in the underground communication network.

The forest does not pause between measurements. Each datum we record is a single frame from an ancient, ongoing process -- root speaking to root, canopy breathing with the wind, the slow chemistry of decay building the architecture of what comes next.
