There are one or two nice people from Switzerland (assuming you are there, just guessing from comments) on bonsainut if you are looking for local resources and helpful people. A decent-sized collection like that is a real testament to unbroken continuity (especially during the growing season where you can't skip a day or even a few hours sometimes), other hobbyists can help you fill the gap when situations come up. Stop by the r/bonsai beginners thread any time if you wanna talk trees!

It affects seedling recruitment for sure. Some species love to start beneath leaf mulch and there is probably something out there that would colonize your leaf field hard and fast if it were given the chance. I collect red alder seedlings in timber clearcutting areas, and often find that they've had to twist/push their way through 6-12" of slash (clearcutting debris) to reach light and finally grow upwards. Quite a few conifers can push upward through many inches of needle duff as well.

I think conserving energy in cold months is close to the biggest factor.

Regarding the dropping of biomass, in both deciduous and evergreen species, some of the substances from the retiring leaves/needles are reclaimed by trees ("retranslocation") and pulled out of the leaf before letting go of the leaf. In species like pines it'll be the second or third (or older, sometimes much older) retiring needles and in species like maple or beech it'll the be the entire foliage. Mass useful to soil ecosystems still falls but the tree grabs what it can in the late months of the year, hence the color change.

One thing the grandparent comment doesn't talk about much is the cost (in sugar) of both building and thereafter maintaining leaves and the related tradeoffs. Building a fully winter-tolerant broadleaf is more expensive sugar-wise than building a winter-interolerant leaf. A sugar maple in Quebec, where the season is shorter than (say) Oregon is going to compete in its niche better if it can attain surface area quickly at the start of the growing season, and that is better done with a winter-intolerant, more relatively delicate leaf. An evergreen leaf takes more time and mass to build and has to have more limited surface area or armor (cuticle) to tolerate such winters.

The title seems inaccurate at time of commenting. This library is called “nv_cluster_lod_builder”

Nanite is Unreal’s implementation of a similar thing. The README even links to Unreal’s implementation in the references section.

Pines have a hard time pulling on the water chain due to their needle design (silhouette/waxy coating). To move water to a location on a pine branch, you usually need needles or a strong tip bud that was already emerging just as the needles were lost (i.e. the needles already drew a lot of sap to that location just before their demise). If at a given junction you can trace to a descendant shoot that is green / has needles, then the live vein traces through that junction. If no descendant shoot with needles, you're looking at dead wood and inspecting under the bark won't find any trace of green cambium, or only fading cambium.

Understood -- the big multinational I was working for employed an immigration law firm that tracked many such crossings, and they practically begged me not to try crossing by land based on their statistics (which suggested a higher probability of trouble in land crossings). I joined that statistic and learned to never take any chances with any part of this.

I am not an immigration lawyer. Something you should be aware of is that when applying for a green card, your status as a Canadian (whether permanent resident or citizen) or as a Brit (ditto) is completely irrelevant. The green card process sees your application solely through the lens of your birth country. The GC backlog for Chinese-born people is very lengthy. So lengthy that it tests the longevity of a visa or a set of visas -- it's not a marathon you want to still be running 15 to 20 years from now.

For that reason, if your goal is ultimately the US, focus on the US, because you will otherwise be adding _many_ years to the process.

One very notable asterisk to the above: If, while applying for a GC, your spouse is from a no-backlog country (born in Canada, UK, or other no-backlog countries), then your application can essentially adopt that country as the birth country, and you can get through the GC process in a relatively short time (all other things equal).

From your perspective "good timing for a green card application" is ASA-F'ing-P.

I am not a lawyer. The transition from TN->GC is possible too under the right (narrow) circumstances. The big tradeoff is not risking travel while within the lifecycle of one TN term, and likely not being able to straddle a GC application across the boundaries of a TN renewal period at all. For some countries of birth, a TN term is not long enough to get through the GC pipeline. But for Canadians born in Canada, ones who have family willing to visit them instead of the other way around, it may be doable. Or for folks born in other countries which have no GC backlog or a short one. YMMV, but I have personally seen someone go L2->TN->GC. An unusual sequence but necessary given the particulars of that case.

Much like the other commenter, I learned to never ever do any of this stuff (ordinary travel or renewals) via land crossings. You can have a major trajectory change to your life on the whims of a border guard who is just having a bad day even if all of your ducks are lined up and perfectly documented by a large multinational. Bend over backwards to avoid land crossings until you can secure yourself a greencard.

It's like TSA pre but for certain steps in the USCIS flow chart.

True. I get the same volunteers (+ thuja + bigleaf + etc) and put quite a few of them into pots.

Eventually though, doug fir reverts back to a sort of weed status later on, when the accumulated effects of human fire suppression causes doug fir to start crowding out other species and interferes with the typical succession pattern. Harder to notice in the PNW, but if you look at NorCal especially, there are areas that would typically be a more open woodland with (say) oak. Instead these are jam-packed with doug fir due to lack of fire. From the perspective of anyone (whether human, animal, or plant) who misses the pre-suppression woodland state that's normally regulated by regular "good" fire, doug fir is indeed a weed. There normally isn't _this_ much of it stretching all the way from Alaska to Mexico.
