Photo: End/beginning of the trail.Photo: A re-sprout, probably from the 1990 freeze?
Or maybe 1972, it is a rather large tree.Photo: Two of them. Good candidates for removal, since there are some healthy oaks below them.Photo: This whole grove should be eradicated. The dense broom should be pulled, not cut. The oaks encouraged, and natives encouraged and introduced.Photo: Eradicating this grove will also improve the view and consequently, the property values.Photo: This looks more like a 40 year old tree.  
See the understory of french broom.Photo: Pull the broom, eradicate the eucalypti, and this becomes an easy to manage oak woodland.Photo: Deep in the broom thicket behind the fence, in what appear to be a vacant lot,  there is a coast live oak being choked out.Photo: The eucalyptus side is ugly and flammable.Photo: This side is nicer, easier to manage.Photo: Future site for native plantings.Photo: The leaf litter is light and dense. Very little air to support rapid combustion.Photo: Redwoods here.Photo: Eucalyptus fire ladder.Photo: Lot's of flammable litter and invasive weedsPhoto: The eucalyptus is a re-sprout. It outcompetes the oaks for water and other nutrients.
The dead branch on top of the oak canopy was likely the result of a falling eucalyptus limb.Photo: Because the eucalyptus does not close it's stomata during drought, transpiration rates remain high even under dwindling moisture conditions.Photo: There is a nest high in the oak canopy.Photo: See the young eucalyptus who jumped the fence?Photo: Already outcompeting the natives for sunlight.Photo: The young eucalyptus is already taller than the much older redwoods. In five years it will be twice as big as it is now.
Using it's extensive and highly efficient root system to feed it's thirst, even under very high soil moisture tensions.Photo: Beautiful tree. Growing in the wrong place.
The oaks below will do much better without the eucalyptus.Photo: RedwoodsPhoto: Beautiful tree growing in the right place.
We need more oaks in Oakland.Photo: This eucalyptus is depriving the native flora of vitally needed water by rapidly depleting the soil of moisture during the dry season, because it does not close it's leaf stomata to economize water loss.Photo: The broom here could be pulled and the eucalyptus tree chipped and spread around any surviving natives.Photo: Spurge and ivyPhoto: Removing the eucalyptus and broom on the left would allow the native forest to fill in.Photo: Eucalyptus dominated area.Photo: This side looks pretty good. Very low maintenance.Photo: Primarily native side.Photo: Primarily native side panorama.Photo: Eucalyptus side panorama.Photo: Eucalyptus panoramaPhoto: Here is a prime spot to expand the native woodland.Photo: Eucalyptus panoramaPhoto: Native, water conscientious trees being suppressed by the eucalyptus.Photo: Eucalypti must have the cambium layer of the stump treated with an herbicide with 180 seconds of cutting, or it will continue to resprout.Photo: Thick stand of eucalypti.Photo: These trees, due to their nature, are difficult to manage with our long dry seasons.Photo: There is a little oak that would greatly benefit from the removal of the invasive eucalypti.Photo: There are two more competing with the french broom.Photo: Another oak seedling.Photo: See the stunted oak, in need of liberation.Photo: Oak seedling.Photo: Coming up on the bridge.Photo: A young oak woodland.Photo: Here the eucalyptus have been eradicated, see the stumps?Photo: Natives flourish once the eucalypti are gone.Photo: The root from this eucalyptus is tearing up the pavement.Photo: Oak saplings.Photo: The ivy needs to be pulled off of this oak.Photo: This seedling is too close to the path.Photo: All the eucalyptus were eradicated from this corner and the oaks are now thriving.Photo: Broom pulling detail needs to hit this in February.Photo: If the broom is pulled next year, in 2015 very little will come back. The new sprouts can be removed by hand.Photo: Wood chips from eradicated eucalyptus make great mulch.Photo: Pull the broom in January and February, instead of cutting it, and it won't come back so densely.Photo: Another beautiful oak tree.Photo: Photo: Photo: If you think it looks bad here under the native trees, wait till you see under the eucalypti.Photo: Oaks are beautiful, pleasant, and low maintenance.Photo: Fabulous trees.Photo: This is really a sweet stretch of trail here.Photo: Oaks on one side, redwoods on the other. This is a beautiful trail.Photo: Photo: See the eucalyptus in the distance.Photo: Photo: The native side is clear of ground fuels with no vegetation management necessary.Photo: This is a tinderbox. Ground fuels, ladder fuels, and plenty of flammable canopy.Photo: The eucalyptus here is actually on top of the oak sapling.Photo: As ugly as this stand is, there are stunted native trees below.Photo: With the eucalypti gone, these native oaks would thrive.Photo: Another eucalyptus on top of an oak.Photo: Eucalyptus bark caught in the oak branchs.Photo: Falling bark and limbs make the native trees more fire prone.
Here a young eucalyptus has fallen.Photo: As thick as these trees are, there are still natives that will fill in after the invasive trees are eradicated.Photo: How lovely?Photo: An oak seedling.Photo: Tinder box. Very difficult and expensive to manage this kind of vegetation.Photo: French broom and eucalyptus combine to form a vegetation management nightmare.Photo: Cut the eucalypti, leave the little oaks.Photo: The entire grove should be eradicated here. The sooner the better.Photo: These trees need some undergrowth cleared, but are no where near as unmanageable as the eucalypti.Photo: Could use some clearing, pull the ivy etc.Photo: Once the eucalypti are eradicated, trees like this will thrive.Photo: More trees on the edge of the grrove.Photo: French broom and eucalyptus. The most flammable and dangerous vegetation combination.Photo: The french broom will inhibit new trees from growing.Photo: This tree needs the broom pulled from around it.Photo: Once clear, the ground beneath the oaks remains relatively maintenance free.Photo: The French broom seems able to grow in the areas disturbed by the eucalyptus litter. That is why I think we only see the thick broom stands near eucalyptus. Although it does tend to take over wherever it gets a foothold.Photo: Clear under the oaks, in August, with no maintenance.Photo: This bank could use a little vegetation management, but I would consider this site to be very light.Photo: Getting next to the eucalyptus, the work changes from light to heavy.Photo: This stand has been managed before. Here I would remove everything close to the smaller natives trees at least. Although complete eradication is probably more cost effective.Photo: Plenty of stunted natives to fill in once the eucalypti are gone.Photo: This grove may belong to the power company.
That is likely the reason it has been "managed."Photo: The little oak on the left could use some liberation!Photo: Managed eucalyptiPhoto: "Managing" this grove means cutting everything less than 5" every few years, collecting all the fallen tree limbs, should include removing most of the leaves and bark on the ground.Photo: Photo: Photo: This oak would be thriving without the eucalypti hogging all the nutrientsPhoto: Cutting eucalyptus without treating the stump with herbicide results in re-sprouts that are even more fire prone than grown trees.Photo: The oaks in the foreground will hold the battle line once the eucalypti and broom is removed.Photo: There are some nice trees around the tower.Photo: Trees on both sides of the tower.Photo: The bank across the trail.
See all the re-sprouts?Photo: Every single one of these trees should be eradicated.Photo: In five years, these sprouts will be 30-40 feet tall.Photo: Oaks are so much easier to manage.Photo: Oak seedling.Photo: More oak seedlings.Photo: The native trees are there already. Eradicate the eucalypti and vegetation management becomes much easier.Photo: The falling bark is a real problem everything growing close to the eucalyptus.Photo: Re-sprouts from untreated stumps.Photo: Close-up of re-sprout.Photo: This whole bank needs some major work.Photo: Re-sprouted broom. Like eucalypti, french broom re-sprouts and grows more vigorously when cut back.Photo: Pull the broom each February and in a few years the oaks will control the vegetation here.Photo: More eucalypti in the distance.Photo: Here is a manzanita under eucalypti, surrounded by broom.Photo: This broom was cut already this year. See how it is already coming back, even during the dry season.Photo: Oak seedling.Photo: oak seedling with a cut broom re-resprouting.Photo: French broom and eucalypti.Photo: An oak seedling growing from the stump of a eucalyptus.Photo: Close up of the Manzanita.Photo: French broom under the oaks.Photo: This is what managed eucalypti look like.Photo: The eucalypti should be eradicated and the broom pulled up by the roots. This bank and ridge would then be manageable.Photo: Panorama of the eucalyptus side of the trail.Photo: The longer availability of water in the dry season from absence of the eucalypti would help these stunted saplings grow.Photo: Plenty of native trees to liberate here.Photo: The other side needs work, but is no where near as bad as the eucalyptus side.Photo: Another smaller tinder box.Photo: Another oak awaiting liberation.Photo: The inevitable pile of perfectly stacked kindling, created by the bark of the blue gum.Photo: This area is overgrown with french broom.Photo: Photo: Photo: Photo: This is corporation yard I think. The broom here is all re-growth from last cutting.Photo: Heavy growth, this will be very dry and flammable in September/October.Photo: Look at this beauty. I think this would be classified as a tree, so it must be a madrone.Photo: It needs as much help as the manzanita/madrone we came across earlier.Photo: See how the broom is re-sprouting from a single cut trunk.Photo: Re-sprouting french broom.Photo: Re-sprouting french broom.Photo: Re-sprouting french broom. See how the blue gum bark gets caught in the underbrush, adding both ground and ladder fuels.Photo: California poppiesPhoto: California poppiesPhoto: DandylionPhoto: California poppies
