I would like us to describe the event and capitalize as much as we can of this opportunity. We still need to get to Bisley 2 and 3. I was able to reach Bisley 1 and walk to the first tower. The tower is standing but sensors and the overall structure of it needs to be assessed and equipment put back together. Solar panels were on the ground, some equipment hanging from the side and wind sensor with tail clipped. > > For the watersheds, the mesh in Bisley 1 was not broken but there's quite a bit of sediment to pull out and weigh.

This is my goal by Monday deadline. To transfer this info to them so they assess and prioritize how to help.

From what I could assess from my visit to east peak and Yunque peak, at least the entrance to icacos didn't look that bad. The cloud forests were not as hit by the event. We were able to do the regular litterfall collection, manual rain collectors were intact and collected for the event, and the East Peak weather station seemed ok. However there were lots of fresh green leaves on the ground at both elfin and palo Colorado stands (with little canopy damage). This should be a nice "fertilization treatment" to those forest, I would think. > > Palm stands are a different story as at that elevation many lost their fronds or came down. > > Road 191 at lower elevation in the periphery of the road kind of up to palo Colorado recreation area was nailed.

Thanks. This is very helpful. We are anxious to get in and sample streams as soon as possible, as we are seeing a NO3 decline in Sonadora, with our in situ real-time sensor. Similar to what we saw after Hugo for about a month in the weekly samples, but did not capture after Georges. It would be very exciting to capture it more widely in the LEF, at all our Tuesday weekly sampling sites. I would then expect the dip to be followed by months of elevated concentrations (or a decade or so in Icacos). My working hypothesis is that the debris in the stream channel provides the dip in NO3 due to microbial immobilization of N during the first days and weeks of decomposition after entry of hurricane debris into the stream. The pulse a few months later in stream chemistry is the watershed response to reduced plant uptake of NO3 and longer-term decomposition of the added debris on the forest floor (as we have already seen in the CTE). The dip in NO3 would not be seen, of course, if another storm comes and washes all the hurricane debris down the mountain and into the sea. >> >> Would it be possible for IITF to help us out with getting access to stream sites as soon as possible for stream sampling? CZO staff could tag along for sampling, or whatever you think might be appropriate. I know you have a lot on your plate right now, and I understand if this is something you can’t deal with! I also might be able to send down some folks from UNH for a week or so to help with cleanup efforts and assessment of litterfall, tree damage, or whatever else would be helpful.
