A rainy birthday zoo visit

Just south of Hilo lies the Panaʻewa Rainforest Zoo & Gardens. It's the only zoo in the United States located in a rainforest, it's free to enter, and in over a dozen years of living in Hilo I…have never visited. Recently there have been discussions about needing to start requiring an entrance fee, and now that I pass by it several times a week for my new job I decided to fix that oversight and visit for my birthday.

Despite the fact that it was pouring down rain today. Actually, even in spite of the rain I still had a fun time. I went with my friend Josh who had visited multiple times before but hadn't been in over a decade, and he was able to point out some of the changes and improvements. I managed to take some surprisingly good photos despite the rain, so have a few of them:

It's not a very large zoo – it took us perhaps a bit under two hours to see everything – but I found that rather nice; I've visited much larger zoos that took all day to see everything, and it does get a little exhausting after a while. This was a refreshingly ‘bite-sized’ zoo.

And it's not like it lacked for interesting animals, either. I'm only showing the better photos I managed to get, but it's got a neat selection of reptiles and amphibians, including several species of poison dart frogs and various chelonians. There are four native Hawaiian birds, the pueo (owl), ʻio (hawk), ʻalalā (crow) and nēnē (goose), multiple primates and a number of brightly-colored tropical birds, some peafowl who roam the park, tigers, emus, and even some binturongs and an alligator.

All in all it was a fun excursion, and with how close and easy to visit it is I'm a bit embarrassed I never visited sooner. I'm actually quite impressed with how well some of the photos I got with my Pixel 9 Pro came out despite the rain (and me juggling an umbrella in one hand), and I'm interested in coming back on a clearer day to spend some more time and see what else I can get.

And altogether that made for a fun and memorable 36th birthday. My birthday hasn't been on a weekend since 2020, and since I'm usually saving vacation time for trips it was nice to have a relaxing day off to myself this year. (Especially after spending a rather chillier and less pleasant rainy day in the field earlier this week.) A hui hou!

A new job with NEON

It's been four weeks since I started my new job with NEON, the National Ecological Observatory Network (managed by Battelle), long enough for me to start settling in and having a chance to catch my breath. There's been a lot to learn. The past few weeks have been a blur of trainings on various data-collection protocols, learning to identifying dozens of plant species, and a procession of trips to various pre-established plots in the rainforest for data collection. (Plus a little bit of lab work.)

Being up at altitude near dawn for mosquito collection is rough, but the dewy grass is incredible.

NEON's mission is to provide a decades-long collection of ecological data from a network of locations across the US, so the various protocols are designed to get that data in a standardized format from diverse locations. There are twenty ‘domains’ across the US (of which we are Domain 20), which may have multiple sites where data is collected (though there's only one site in Hawaii). This data is open-source and available for anyone to use, a fact which fits my personal leanings very nicely. (Having an ORCiD already set up from my time in astronomy proved useful as we use them for attaching credit to data collection, so I may be able see data I've collected used and attributed in future papers.)

Some Astelia menziesiana (an endemic lilly) on a log.

Collecting such data isn't necessarily easy, though! In addition to the simple fact of the collections sites being located around 5,000–6,000 ft (~1,500–1,800 m) up the side of Mauna Loa, the nature of many protocols involves strict time sampling restrictions, which might require spending the day working in rain. (We're supposed to evacuate in thunderstorms, but those are rare near Hilo.) Even without rain spending 6+ hours in the field is no joke; some plots may have a lot of hard lava rock underfoot, while others (especially with feral pigs present) may be slippery mudholes. I've been amazed by the number of fallen logs in some of the older sections of the forest, which combined with the undergrowth can make getting around something of a challenge. We work four 10-hour days, and while the three-day weekend is nice there's no denying that working that long can be grueling, especially on field days.

Still, it's not without its upsides. While it can be uncomfortably hot, cold, or wet at times, at others it can be fairly pleasant. The work itself is interesting; while I had some experience identifying plants before, I'm learning all kinds of new, native plant species, and finding them for the plant diversity protocol is rather like a treasure hunt. Depending on the plot, we might find trees some 500 years old, or be exploring relatively younger lava flows from Mauna Loa perhaps a mere 250 years old. There's little human presence in the Natural Area Reserve where we work (although it's technically open for hiking), and the still-intact native forests house native birds which are rare elsewhere.

We often see nēnē at the site; I think I saw more my first day than in all my time here previously.

I've also found the labwork, though a far cry from anything I've done before, to be interesting. So far I've sorted leaf-litter from our leaf-litter traps, seeing how the distribution of species varies from plot to plot, and identified beetles from our beetle traps. The particular beetles we're interested in are called carabids, and while most species on the mainland are ground beetles, our native Hawaiian species are arboreal (though we still manage to catch them in our ground traps, somehow). There have actually been two entirely new species found in our traps in years past, which is certainly an exciting prospect.

Leaf litter sorting, into various piles for things like leaves, flower, seeds, twigs, etc.

After four weeks I'm not sure if this is something I want to continue doing indefinitely, but I've got a wonderful group of motivated, clever, and fun coworkers to work with and there are certainly fascinating aspects to the project and sights I wouldn't see otherwise. Perhaps I'll feel differently after a few more months. We'll see! A hui hou!
