The problem is that most people only wants to plant rapid growth trees like eucalyptus, because they can give profit in 7 to 10 years, unlike oaks and other trees, that only grandchildren will profit. And that´s because there is not yet a good forestry policy supporting a sustainable forest (too many economic´s interest). Let´s hope it can be better in the future. By the way, isolated, old eucalyptus trees can be beautiful, but we should be aware of the fire risk, and the abundant self-germination capacity that the seed have been showing after fires.<br />npedronoreply@blogger.comtag:blogger.com,1999:blog-5223294603002782762.post-84469859596494222662017-02-01T20:47:01.075-08:002017-02-01T20:47:01.075-08:00I live in the home of the eucalyptus and the acaci...I live in the home of the eucalyptus and the acacia and they are incredibly overrated. Eucs are allelopathic, most are ugly, they discharge limbs over all and sundry, 8% volatile oil, messy, negative impact on soil structure....I could go on, but it is disgraceful how it is legislated that we must live within a fire dependent eco-system by many councils and state and federal law.

The fast money mindset of people eventually is going to doom them... They do and do not help the water situation, knowing the country well I can assure you that places where there was oak instead of them were far more damp... the last government allowed free planting of the trees, the actual one forbidden planting them (a measure that is being met with hatred by the common idiot culprits), it's time there is a change... About Cortaderia, it's hell... there is no other way to describe it, also water hyacinths and ailanthus... those introduced by the so called responsible people...

In New England and south to Washington last year, we saw vast tracts of Japanese Knotweed.

The forage was from mountain sides of some kind of Acacia, cut and hauled to the goat facilities. Not sure what the salable product was: meat or milk/cheese. Probably the former. An idea for Portugal? Figure out a marketable use for cutting/removing/coppicing the invasives?Kate Kruesihttps://www.blogger.com/profile/05750131133931902097noreply@blogger.comtag:blogger.com,1999:blog-5223294603002782762.post-68778571019855193512017-01-05T13:43:49.901-08:002017-01-05T13:43:49.901-08:00In South Africa we have similar issues with eucaly...In South Africa we have similar issues with eucalyptus and Australian acacias.<br />Currently some furious mountain fires and seven houses destroyed.<br /><br />But we are making steady progress removing the pine plantation at Tokai, to restore the fynbos. Wonderful to see the plants ARE returning from the seed bank, once the invasives are cleared. Also the streams flow again, once the eucalyptus and pines aren't drinking all the water.Diana Studerhttps://www.blogger.com/profile/12286066768376135880noreply@blogger.comtag:blogger.com,1999:blog-5223294603002782762.post-5252103001624965782017-01-05T07:53:46.123-08:002017-01-05T07:53:46.123-08:00Last October we had a wonderful holiday in Villasi...Last October we had a wonderful holiday in Villasimius Sardinia. It was a joy to walk the maritime landscape and observe the wonderful diversity of plants.

On a two week driving holiday on Madeira I was astonished to see huge tracts of them and thought they were just a quirk of nature them being present on the island (on a lot of the higher slopes in the centre of the island) and very pleasant to walk through on a hot summer day actually - but I guess these are not native here either. And of course they have had some terrible forest fires.Ed Corbett Jr.https://www.blogger.com/profile/18394365299148426370noreply@blogger.comtag:blogger.com,1999:blog-5223294603002782762.post-27710953169888881472017-01-05T02:34:43.637-08:002017-01-05T02:34:43.637-08:00I had not really appreciated many of the negatives...I had not really appreciated many of the negatives you mentioned in this blog.One further thought is that the aesthetics of the trees is not great.
