why is Forest Industry importing? (solved)

[Nite69]

I have it located in a heavy dense tree area so they can get the lumber they need but its still importing

Oil, Agricultural, and Ore are very low imports and are working as they should.

edit: I fixed it, the forestry wasn't detecting the nearby trees ya have to build the industry over the top of them

well I don't want to bann it completely, thats cheating :p I just want to figure out why its importing when I have forest industry running, Its not lack of Forestry Supply, my City is making what it needs, I tested this with adding more forestly and import got worse on it when I did it

Do you have the Industries DLC? If so, it will peter out eventually. Make sure that you have warehouses to hold lumber products from regular forestry areas and planed lumber, as well log yards for holding logs to use for your paper mill, saw mill, engineered wood products, etc. Set warehouses to balanced at minimum or empty. I seem to recall that helps to keep from importing, but it also means trucks are unavaliable for keeping plants stocked with supplies if they are exporting to outside connections. I make a killing on warehouses.

Not sure about the DLC but the only forestry areas in vanilla (and I have almost all forestry in my cities) are ones on DENSE FORESTS. If you just have a few trees and build on that you have "forestry" that needs to import because they are making lumber out of trees -- and not grown trees.

So if that follows through in your scenario and your later comment seems to suggest that -- it may be what is going on. Look and see if your forestry areas are GROWING trees (I live in a forestry community in RL :D). Mine that have lots of tree lots are exporting twice as much as they are using in their own city (and I have GREEN CITIES so much is consumed close to home as a mandate)>

No I don't have the industry DLC, and I made sure to put in plenty of trees around the forestry district, confirmed by looking at the natural resources and the map got darker green around it

I think I might have an idea what the cause is, when I built the forestry district, no trees were around it, and I then later added trees around the forestry block. so what I am gonna try doing is, removing the forestly industry blocks, place a bunch of trees in its place, and then readd the industry zone to it and see what happens

Yep thats what it was, I fixed it, the forestry wasn't detecting the nearby trees ya have to build the industry over the top of them

No, what happened here is Nite69 placed the forestry industry beside the stand of trees instead on top of the stand of trees. If you view through the resource view the trees leave a green resource marking patch. On the green is where you must place the industry or they will be forced to import. Placing trees first before making the forestry industry is something that I do to extend the forest industries size. And yes you can plop a stand of trees then make a forestry industry out of it.

Could it also be that if no trees were in place when the industry first grew then they would be generated as processors. When adding trees later, I don't think the buildings automatically change to extractors? I think you need to delete the processors and then they re-generate back as extractors, which sounds much like what Nite69 described in the #5 post.

Yes. If there are no trees around and you make a forestry district, you get sawmills and not tree farms. To get tree farms from the beginning, you need to have some trees there to start with, even if it is a light green.

Now, with the Industries DLC, I have noticed that the extractors produce more of resources if the area is a more solid color such as dark grey or all black for ore and oil compared to a lighter color of said resources.

For a VISUAL (and partly because I am just learning how to get screenshots in here :D) -- a shot of placement of industry OVER forested land. This produces tree lots (I have seen this area in almost solid trees at times).

If you look at the far left you will see some trees that I placed with the landscape tool on land THAT DID NOT HAVE TREES NATURALLY. Landscaping trees do not affect the soil. You want the soil that naturally grows trees and plunking down landscaped trees doesn't do that :D. So only lumber mills and yards will spawn on non or low quality tree producing soil.

The trees seem to be easier to deal with than the farming. For farming you REALLY need the land to be yellow in order to get crops. Hoping this screenshot produces a thumbnail :D

I will take and plant trees like alder, beech, oak and all the green tree varieties in places that had pollution from polluting industries to help clean the area faster as well as to create forested areas to have a forestry industry there later. Sugar maples will work as well.

I am not sure about flowering trees though.

I am not sure that the landscape trees we add do anything other than look pretty. Maybe some oldtimers can chime in and advise. I just put them up to look nice. They are cheap. I wish there were more to pick from though :D.

Forestry and farming don't pollute which is why they are the only industries I use. But yes at the beginning we get polluters in there. Once you get ALL there is to learn (so much) squared away I suggest that you might like the GREEN CITIES add on as there are several important things in there that really help with pollution. "I" also like the buildings better -- but that's a taste thing.

Good luck with your city!!!

PS a few minutes later. Trees won't grow on polluted land and those that were there nearby die quickly -- even just slightly polluted land. So that plan can't work as far as I can tell. Time disperses the pollution and The Eden Project is a big help with that. Eventually between the two most all pollution is gone. This is a fair ways into a city though :D.

As a couple of old timers, myself and OneJasonBradly have already chimed in. We have both observed/experienced the benefit of planting trees. But you are right that the more trees you plant closer together (and therefore the darker the green in the resource overlay) the more likely you get extractors rather than producers.

One thing that may not be so apparent is that building roads on top of trees does not affect the resource rating. So if you are going to create a forest area for mining then place the trees first and then the roads on top of the trees. If you place the roads first then you obviously can't then place trees where the roads are so the resource area is less intense. Hope that makes sense.

OK so you CAN "build a forest area"? But the comment about using trees to fix pollution can't really work, can it? Keep planting trees and then bulldoze dead stumps and then plant more trees? Rinse and repeat? :D. Thanks for the input. I didn't get that from the original comments.

Didn't notice the pollution comment. No, it won't clear industrial pollution. But trees will help reduce noise pollution. Again, the more dense the trees, the greater the noise reduction effect.

As you mention pollution kills trees, so the bulldoze/re-plant method will not clean up pollution.
