Native seed not best for restoring native plants

When a native plant population has declined drastically, the remaining plants become inbred. While these inbred plants clearly have what it takes to get through what ever caused the decline, seed supplies can be small and inbred in ways not beneficial to restoring a population.

The answer to successful revegetation of native flora is in sourcing genetically diverse seed, not necessarily relying on seed sourced from remnant local native vegetation.
“A common belief is that local native plants are the best source of seed for revegetation projects,” says CSIRO Plant Industry scientist, Dr Linda Broadhurst, “It has been presumed that local seed is adapted to local conditions and therefore provides the best results for restoration projects.

“However, the research shows that where vegetation loss is high and across large areas, ‘local’ seed sources are often small and isolated and can be severely inbred resulting in poor seed crops.

“This can lead to germination failure and poor seedling growth.”

The findings are based on a review the results of which have been published in an article entitled; ‘Seed supply for broadscale restoration: maximising evolutionary potential’ which appears in the latest edition of the journal, Evolutionary Applications. . . . read more “Local see not best for revegetation

  1. “However, the research shows that where vegetation loss is high and across large areas, ‘local’ seed sources are often small and isolated and can be severely inbred resulting in poor seed crops.”

    By inbred do they mean like first cousins? I thought that only happened in Arkansas.

  2. lol, funny thing is current research shows it’s a good thing to mate with your cousin. Though that seems to be one of those things that works on paper but not in real life.

    How’ve you been?

  3. Good. I’m psyched up for spring. To me, it starts on March 1.

    My pentas made it through the winter nicely. I think 30 was about the low temperature in my garden. I guess that’s the good side of global warming.

    My impatiens made it through winter too and are blooming, even though they are mostly in pots. My Mexican zinnias are blooming too. And so is my knockout rose. It bloomed all winter. And my mexican heather plants bloomed all through winter too, both the purple ones and the white ones.

    Last fall I bought a lemon yellow zinnita zinnia and was surprised the freeze didn’t kill it. It’s doing nicely and I plan to get some more. I like zinnita. It seems to get a but taller than profusion zinnia.

    I have a couple of scarlet sage with variegated leaves. Scarlet sage is sold as an annual but it made it through winter nicely in my garden even though both plants were in pots.

    As you can probably tell, I really like having a variety of flowers in winter.

  4. So far it looks like an alocasia is the only victim of winter. Of course Ike did so much damage winter seemed like a break for the plants.

    My pentas has been blooming for several weeks, too but it took most of the winter off. The castor bean, Mexican bleeding heart and roses bloomed all winter. The nun’s orchid put out a few half hearted blooms this week.

    I’m finding it hard not going out and trimming the frost burned parts off the delicate plants. It’s likely we’ll get another cold spell before all is done for the year.

    I put tomatoes out in pots. I know it’s early but thought I’d try anyhow. Right now they are small enough keep protected under bottomless plastic bottles.

    Global warming is very good for gardeners, and Yankees.

    I’ve had no luck with sage, it grows for me but never lasts more than a year. Your scarlet sage must be beautiful, it’s amazing the bright reds in the flowers down here.

    Zinnias come in such cool colors, I bet they really brighten up the garden in winter.

    My poppies came up, the last two years my seeds failed. ( or I thought they were weeds and yanked ’em before they grew up ). I fell in love with them when I want to Austin last spring and am hoping for a good display.
