Author Topic: The current version of the bayberry tree is pretty unhinged from reality  (Read 1948 times)

Spoiler (click to show/hide)

Like it says in the comments, it's supposed to be a combination between Myrica rubra and the Myrica gale. A totally reasonable way to go about things, as far as modeling trees and creatures in Dwarf Fortress goes, but this pair is incompatible with all reason.

M.gale (swamp myrtle) is a leafy tree-shrub thing that grows 1-2m tall and grows in bogs in the chillier and more marine parts of Europe. It has a few sorta-herbal uses, but for the most part is just sort of there.
M.rubra (chinese bayberry) is a big honking fruit tree that's been actively cultivated in the slopier bits of China and Japan since time immemorial for its sweet, delicious and precious fruit. It's also called the mountain peach.

But look at the raws above, the combo ended up as great big tropical fruit trees that grow in nearly any climate whatsoever. It sometimes makes up most of a world's (sub)arctic taiga, which by definition should be almost nothing but big hardy conifer trees. Pines and fir.

Its real-life niche of "forests on mountain slopes and valleys at altitudes of 100–1500 m" needs some interpreting, but the point is that it doesn't include the arctic circle. Just limit it to the tropics and it makes much more sense.

Is it too much of a stretch to imagine that the history of dwarven cultivation of the bayberry might have taken a different course than in our world? That the dwarves somehow unknowingly encouraged the tree to adapt to extreme climates?

Ummmm...

There are two kinds of plants in the DF world: real-life plants, which are supposed to be modeled pretty accurately, and fantasy plants, like fisher berries, creepy eyegrass, and highwood.

Toady's set a good precedent with his modeling of real-life plants. Hell, the Bay12 community actually researched the density of saguaro wood in order to make the simulation more accurate.

If Toady wanted to make a fantasy tree that acted like this bayberry tree does, I'd be fine. But he's calling it a "bayberry," and it doesn't act like a bayberry. That is wrong and probably a mistake. This fine individual noted that and is informing Toady of this fact.

Good job, sir Scamtank, fine example of Bay12ers, carrying on the tradition of the cactus-measurers.

Within the boundaries of dwarf fortress logic, my reasoning would be that because the dwarves and livestock are so fond of the fruits of the DF'world bayberry tree, they regularly excrement the seeds when they embark on journey's passively, this would explain a lot of sudden sapling growth post embarkation upon a typically desolate place (such as exposing bare tiles in a tundra to create 'grass' in which saplings compete for space for)

For hating trees so much, ironically dwarves (because goblins and elves dont nearly get out so much and humans dont really care as long as its typically aboveground and flat) are the worlds greatest pollinators and in some ways Armok's instrument for bringing life (and summary death and bloodshed) to the world.

Excellent flavour for the bug.

However, I will note that many forumites produced such stories for the "adventurer ambushed every two freaking seconds" bug. It was definitively a bug. So don't let your fondness obscure the bugginess.

"Everything occurs everywhere" is a problem that DF has in droves.  At least, it's starting to be stratified into "tropical" and "temperate" being two different things, but beyond that, everything is wild.  (As in a tropical swamp plant will not grow in a temperate swamp, but will grow perfectly fine in a completely waterless tropical desert, or off the sides of a stony mountain in the tropics.) Hence, jute, which in real life only can be cultivated in India or places nearby because it is evolved solely for monsoon rains, can grow literally anywhere tropical. 

It's also a problem when you consider many animals and plants naturally evolved together.  Australia, for example, has fauna completely different from most of the rest of the world, which could only exist as it does in isolation from the rest of the world's fauna, but they all just sort of get mashed together into the same temperature bands, here.

I do not think of DF plants/animals as actually being the RL plants/animals, more parallel evolved plants/animals that are basically similar; so there is no reason to think the in-game bayberry is really either species of really existing bayberry tree.

Are you saying there's no reason to think bayberries are realistic just because you assume DF plants aren't?

Toady's intent could just as easily be the most commonly eaten variety of the time period, and made a mistake. The man is known to enjoy historical accuracies. I think we should probably hear Toady's opinion before jumping to any conclusions.

If that's what he wanted to do, he would have stuck with rope reeds, rather than adding jute, and he wouldn't have been interested in someone actually requesting samples of saguaro ribs just to test their density. 

Toady even has said that he wants things to be hyper-realistic just because he wants to surprise people when things happen how they would in real life, not in "gamey" ways.  It is hard to square the notion that his fastidious attention to detail to make everything he can as accurate to real life as possible with a notion that it's all a charade because he doesn't care about things being accurate.

IMO, the root (heh) of this is DF's slipshod biome-related raw tokens and the plants & creatures that use them for placement. Even the embark screen distinguishes more between biomes than the raw tokens do. Bayberries are "temperate" because the only other options are "tropical", "desert", or "freezing". There's just no way to specify a subtropical climate in the raws.

(No idea why he put them in the taiga though.)

I'm sure Toady already knows that this needs improvement, but it's my impression from working with the plant raws that he burned out on plants during the lead-up to the 0.40 release. It'll probably be a while before it's fixed.
