  • What are some good, casual mobile games.

  • I don't think I saw this game mentioned here yet, so I'll recommend SmashHit. It's a game about throwing metal balls at glass and not getting hit by said glass. It's not a typical "casual" game but it still fits the criteria pretty well, especially with its "ethereal" atmosphere.

    It's unfortunately only on the Play Store, but you should be able to get it through the Aurora Store no problem.

  • Oh man, don't even get me started on the temperatures. While trees can sense the length of day and night and use that to decide when to bloom, temperature also plays quite a big part, and a warm March or god forbid a warm February can do quite some damage, especially in tree nurseries and young stands. Insects don't rely on the length of day as much, so this winter we've had a few cases where the insects emerged early and likely didn't survive when the next cold spell hit.

    Does the breeding season shift in birds have any big effects, by the way? My ornithology amounts to watching pigeons and jackdaws on the campus grounds, so I'd love to hear more!

    I think it was the Emerald Ash Borer that has been doing a number here.

    Oh, the Agrilus genus! I really like buprestid beetles for their looks and it's a big shame that most of them are some really nasty pests. That view of the Smokies sounds absolutely haunting. Especially given that everything on your side of the pond is much bigger. Losing like 50 hectares of forest would be a tragedy over here, while in the States it's probably not the end of the world. Though, losing 80% of the trees is cataclysmic, to say the least.

    And good luck with that property! Forestry and its processes take place over decades, so it will be a long time before the place goes back to its former glory.

    Best of luck with your studies, and whenever you have tree knowledge to share, continue to do so!

    Yessir! And thank you for keeping this place alive! This comm is genuinely a cornerstone of Lemmy for me and your contributions can't be appreciated enough!

  • Polish forestry from what I've heard is one of the best in Europe, if not the entire world even! Getting actual definitive and comprehensive data for that claim is really difficult (especially with how search engines have enshittified nowadays), but based on some other data I've seen (like how Poland has the highest sapling production in Europe) I'd still say our forestry is really good.

    As for our efforts, I'd say we're doing well! That doesn't mean we don't have problems, however, and our biggest problems right now are (from the top of my head):

    • Cllimate change, adapting to which is quite difficult. The following changes come to mind:
      • Changes in habitable zones for multiple species of trees, which might cause some of them to disappear from Poland entirely (Abies alba, the silver fir, is a good example, and their recession from the country has been observed for the past few years)
      • Rising climate instability will lead to more extreme weather patterns, which will put more stress on our forest stands, which in turn will reduce their yield, both in timber and genetic material, and will make them more susceptible to pathogenic entities, such as fungi, viruses, or insects
      • Speaking of pathogens, the rising overall temperature will introduce new species of pathogens into our country, which otherwise would not have survived due to our colder climate. Fungi in particular come to mind. Some insect species will also migrate to the country as a result of climate change.
      • Climate change will also likely make our droughts even worse, further worsening our stands' health
    • The previously mentioned fungi are also causing a bit of havoc in our stands. While I'm not far enough into my phytopathology course to give a lot of info there, I can say that there are some pretty nasty tree diseases going around. Today we had a lecture on the Heterobasidion genus of fungi, which attacks tree roots, and is usually asymptomatic until it's far too late. One particular species of Heterobasidion, H. annosum sensu stricto, also has a very wide range of hosts (in comparison to i.e. H. parviporum and H. abietinum, which attack a very small set of tree species). Yearly, that single genus alone causes up to 800 million Euros in losses related to forestry (across the EU - I don't have numbers for Poland)
    • We're also still fighting our old practices back from the Warsaw Pact era, where forestry education wasn't as widespread and the field simply amounted to felling trees and selling the timber. In relation to that, we're also increasingly moving away from using chemicals to deter pests and infectious agents, which forces us to come up with new methods for counteracting these two, or simply paying foresters more to do things the old fashioned way (physically go into the field to monitor the stand and act on any stressors)
      • And speaking of old practices, pine monocultures are in fact very bad! On top of that, those monocultures were felled in one single operation, which exposed the entire field after the timber was moved out. This caused soil decay and lowered ground water levels, on top of destroying what little biodiversity was left in that pine monoculture. While an embarrassing amount of fields still follow this mindset (around 25-40%), we're slowly moving away from that in favor of planting multiple species of trees in a stand alongside felling only a select few of them in order to keep the stand stable. Multi-species stands are more resistant to various pathogens and also to extreme weather conditions.

    And that's just all I could list in the like half an hour it took me to write this! Despite all that we're doing very well and hopefully we'll be able to adapt to climate change in the future.

  • I didn't have Pinus jeffreyi on my course, unlike P. ponderosa, but from a brief glance at the morphology I would say this is probably a P. ponderosa cone, more or less based on the spikes. Without other characteristics, like the needles, it's much harder to say for certain.

    The size is a bit odd but it wouldn't be out of the question especially if the growing conditions were optimal (which for Lake Tahoe seems very likely), and the tree was quite old (again, very likely for Tahoe (at least I think))

    And I'm glad I can be of use! My course covers mostly the Polish dendroflora with a bit of overall European flora here and there, but in the case of pines specifically we're given a bit more info on them simply because they're so important to Polish forestry (iirc 65-70% forest coverage is just pine, of which >90% more or less should be Pinus sylvestris)

  • That's a big pinecone! Assuming this is from the US this should be a cone from a Pinus ponderosa, the yellow pine. Based mostly on the spikes on the scale plates, the size, and the fact its one of the most common North American trees.
