Robert Pallin, son of the late Paddy Pallin, is a member of the Lord Howe Island Board and was talking passionately about preserving bushland and removing weeds.
Here is a link to a recent story about weed eradication on LHI:
wild.com.au/news/lord-howe-island-weed-control/
I went to LHI as part of a fundraising trip for the Climate Council of Australia:
A weed control contractor is applying a watery spray of triazine and bromocil, which inhibit photosynthesis, effectively starving the weeds and grasses to death. The spray is non-toxic; the contractor needs no mask or other special protection; even when still wet, the spray is harmless to people and animals..
Lowland rice weeds / POACEAE (grass family)
Weed name : Paspalurn distichurn L.

SF Bay RR, 21 June 2018
The San Francisco Bay RR operates on the southeast side of San Francisco on and near the port. It uses two Alco S2 switchers that were built for the State Belt RR, later the San Francisco Belt RR, the line that served the piers of the Port of San Francisco for many years.
As shipping companies moved to containerization, the Port of Oakland became the big northern California container terminal and most of the piers of the Port of San Francisco were abandoned or converted to uses other than marine freight, so the SF Belt RR found itself out of a job. After 1989 Loma Prieta earthquake damaged the Embarcadero Freeway, which had run over the SF Belt for most of its length, the freeway was removed, opening up San Francisco's waterfront and much of the Belt's trackage as converted for use by the Muni F line, which runs historic streetcars to Fishermen's Wharf, and the Muni lines that now server the Caltrain station.
Meanwhile, Pier 96, near Hunter's Point was converted to a container facility and the railroad's operations survived there. The line was renamed the San Francisco Bay RR and continued to use Alco S2s 23 and 25 to switch its customers.
Today, the railroad's main business is transloading dirty dirt from constructions and clean up sites in the Bay Area from trucks to railcars. It is owned by Waste Solutions Group, which also owns a fleet of hopper cars. The SF Bay and UP interchange on an as needed basis, with UP's South City job running into the SF Bay's yard on Cargo Way with empties and taking away loads.
A couple of railfans, Ryan and Ben, work for the railroad and Ryan invited me to come by for a visit. I had stopped by one afternoon a couple of years ago, and lucked out to see an S2 running around the yard a bit, but the railrroad usually goes on duty betweeen 4 and 5 am, switches cars for a few hours and then is done for the day. So, a visit to the SF Bay from Sacramento entailed a night in a hotel. It took a few tries for me to get time off from work scheduled on the same day the railroad was running.
Eventually, it all lined up and my alarm went off at 0315 at a hotel in Daly City, just south of the SF city limit.
I was at the yard by 4 and met Ben, who went out and started Alco 23. 25 is out of service with a bad bearing on the radiator fan drive shaft. Ryan explained that the SF Belt had done a jerry rigged repair of the shaft at some point and it was never documented, so nobody knew about the bearing until it failed. As a new low emission unit will be delivered in the next few months, there is no reason to repair 25. 25 will be put on display somewhere, perhaps near the Ferry Building, while 23 will be held as backup for the new unit.
But for now, an S2 built in 1944 is doing the job it was built to do. If you think about it, that is as though the Virginia and Truckee had still been using the Reno and Genoa during WW2.
Shorty after I got there, Ben went out and fired up the 23. It has a block heater, so it started easily with a puff of white smoke. He did an inspection of the engine, including checking the journal boxes. We then went back into the office and waited for Ryan, brakeman Johnny, and engineer Nick to arrive. The crew plotted their switching moves for the day. Ryan, who is yard operations manager, suggested that I get some blue hour photos from the ground as empties were switched and then we rode 23 while they switched loads.
Each car has dirt from one particular construction site and the dirt from sites cannot be mixed as different sites will have different contamination. UP ships it to a dump site in Nevada, where it is processed. Ryan explained that sometimes they can use dividers in a car to separate dirt from different projects if there is not that much.
Right now transshipping dirty dirt is the SF Bay's only business, but there a couple of other industries are interested in bringing new business. The line that crosses the Illinois St. bridge has been out of service for a couple of years as there currently no customers north of Islais Creek.
We rode the S2 for a while after the day brightened, then got down and Ryan drove me around in a company car to get some more angles as they switched. He then had other work to do and I shot the end of 23's work day as well as 25, some spare Alco parts and another project of Waste Solutions, goats that are leased out for natural weed control. Ryan said that since Waste Solutions got more cars, they can't use their goats as much for weed control in the yard as most of the yard tracks are occupied.
The crew called it a day for switching about 0800 and then would be doing other work in the yard for the rest of their work day.
All of these photos were taken with permission after signing a release and while wearing required PPE.
I want to than Ryan, Ben, Johnny and Nick for their hospitality. I had a great time.
Red Hill Nature Reserve - only 2km from the nation's parliament. Local native plants in the photo include: Blakely's Red Gum, Yellow Box, Silver Wattle, Drooping She-Oak, Dianella and Poa grass. This is nationally endangered Yellow Box-Red Gum Grassy Woodland. Invasive weed control by Parkcare volunteers, Parks and Conservation Service Rangers and Contractors, has protected this area for future generations.
Q: What’s your role in addressing this invasive species issue?
A: I am a member of the Watershed Protection and Restoration Branch of the Environmental Assessment and Restoration Division in the Washington Fish and Wildlife Office in Lacey, WA. I manage restoration projects funded by the Partners for Fish and Wildlife Program and Puget Sound Coastal Program addressing the control and management of invasive nonnative plants. We have funded projects addressing the control of common cordgrass or Spartina (Spartina anglica), knotweed (Polygonum spp.), yellow flag iris (Iris pseudacorus), purple loosestrife (Lythrum salicaria), reed canarygrass (Phalaris arundinacea), blackberry (Rubus spp.) and invasive cattails such as lesser cattail (Typha angustifolia) and hybrid cattail (T. x glauca).
Q: Who are some key partners?
A: We have partnered with Washington Department of Fish and Wildlife, the Center for Natural Lands Management, North Olympic Salmon Coalition, The Nature Conservancy, Lummi Indian Business Council, Skagit Fisheries Enhancement Group, and Thurston County Noxious Weed Control.
Q: How do you stay positive given such a daunting challenge?
A: I think the new tools added to the invasive plant control toolbox every year are a big help, as well as a very energetic group of folks addressing the problem. As they say, "there is strength in numbers."
Q: What’s one success (so far, if warranted) with this effort that makes you particularly optimistic?
A: I think the near eradication of Spartina in Willapa Bay, WA and Grays Harbor, WA (of which we played a small role) is one of the most visible successes in the PNW.

"To increase the effectiveness of the weed control product, keep children and pets off the lawn for 24-48 hours after an application of Weed Man weed control product"
I've recently started shooting all the "No Spray"/"No Poison" signs in my neighborhood, and made this montage from 13 of them.
In Hawaii, it's common for folks to make and display "No Spray" signs along the road to prevent government weed-control crews from spraying herbicide on their roadside plantings. I've shot photos of over 30 such signs so far, and I've only covered our neighborhood.

Until the latter half of the 20Th century, sugar beet production was highly labor-intensive, as weed control was managed by densely planting the crop, which then had to be manually thinned two or three times during the growing season.

Beth Hoinacki, owner of Goodfoot Farm located northwest of Corvallis, Ore., has four Babydoll Southdown sheep, in addition to geese and chickens, incorporated into the pest management plan and nutrient management plan of her organic farming operation. The combination of sheep and birds reduce mowing through grazing and provide weed control as well as insect and plant disease management through foraging and cultivating all the while improving soil fertility with their manure. The skid design of the shelter and the use of electrified fencing also allow easy transport to different areas on the farm where the animals are rotated as needed.
Beth is participating in the Natural Resources Conservation Service (NRCS) Environmental Quality Incentives Program (EQIP) Organic Initiative. Pest management is one practice covered under the program. For more information on Organic EQIP and other conservation opportunities, see your local NRCS representative.

This book defines "weed" as:
A plant growing where it is not desired. Any plant that is a nuisance, hazard, or causes injury to human, animals, or the desired crop.
In other words, it is a political term.
This book is about using pesticides and herbicides.

This hardy, fast-growing plant is on the hit list of weed control efforts around the globe. It's an aggressive, exotic invasive species that quickly takes over roadsides, stream banks, and other areas, excluding native species and dramatically reducing biodiversity. The plant was at one time popular as an ornamental. These days, intentional or accidental introduction of the plant has been banned in many European countries and in many states and counties in the United States. Here's one exotic that many would like to be without!
Our Daily Challenge: Exotic
Advice on controlling weeds from the Community IPM Working Group, funded by the Northeastern IPM Center. www.northeastipm.org
I had originally set the tractor wheels as close together as the would go in order to get the most rows onto the field. We have recently been using more plastic film for weed control and to warm up the soil in the spring. The wheel spacing was too narrow to go over the plastic for cultivation without damaging the plastic. So I had to move the wheels out.
The wheels are designed to be mounted in any of four positions, so there are eight possible wheel spacings. The note shows one of the flanges mounting the tire to the hub. The narrowest spacing is when the tire is mounted on the inside of the hub (using the bolt hole on the right in the note). Here I have moved the wheel out one notch. I did the same on the other side. That changes the spacing by about 2.5 inches on each side, 5 inches total.
To get the other two positions, the hub is also removed and turned around. It has a slight dish shape inward here. Moving it so the dish is outward gives you the other two positions.
Moving the wheels was fairly simple, but aligning the front wheels afterwards took two days.
Mark Bernards, Western Illinois University Assistant Professor of Agronomy, Crop Science, and Weed Control, spoke to the crowd about yellow flash and herbicide interactions.
The 2013 36th Annual Greenley Memorial Research Center Field Day was held on Aug. 6. Breakfast was served at 7 a.m. followed by a day of educational tours. Topics covered included information for landowners about the effects of flooding on crops, tillage radish management, ways to waste less hay and common pest problems encountered.

SF Bay RR, 21 June 2018
The San Francisco Bay RR operates on the southeast side of San Francisco on and near the port. It uses two Alco S2 switchers that were built for the State Belt RR, later the San Francisco Belt RR, the line that served the piers of the Port of San Francisco for many years.
As shipping companies moved to containerization, the Port of Oakland became the big northern California container terminal and most of the piers of the Port of San Francisco were abandoned or converted to uses other than marine freight, so the SF Belt RR found itself out of a job. After 1989 Loma Prieta earthquake damaged the Embarcadero Freeway, which had run over the SF Belt for most of its length, the freeway was removed, opening up San Francisco's waterfront and much of the Belt's trackage as converted for use by the Muni F line, which runs historic streetcars to Fishermen's Wharf, and the Muni lines that now server the Caltrain station.
Meanwhile, Pier 96, near Hunter's Point was converted to a container facility and the railroad's operations survived there. The line was renamed the San Francisco Bay RR and continued to use Alco S2s 23 and 25 to switch its customers.
Today, the railroad's main business is transloading dirty dirt from constructions and clean up sites in the Bay Area from trucks to railcars. It is owned by Waste Solutions Group, which also owns a fleet of hopper cars. The SF Bay and UP interchange on an as needed basis, with UP's South City job running into the SF Bay's yard on Cargo Way with empties and taking away loads.
A couple of railfans, Ryan and Ben, work for the railroad and Ryan invited me to come by for a visit. I had stopped by one afternoon a couple of years ago, and lucked out to see an S2 running around the yard a bit, but the railrroad usually goes on duty betweeen 4 and 5 am, switches cars for a few hours and then is done for the day. So, a visit to the SF Bay from Sacramento entailed a night in a hotel. It took a few tries for me to get time off from work scheduled on the same day the railroad was running.
Eventually, it all lined up and my alarm went off at 0315 at a hotel in Daly City, just south of the SF city limit.
I was at the yard by 4 and met Ben, who went out and started Alco 23. 25 is out of service with a bad bearing on the radiator fan drive shaft. Ryan explained that the SF Belt had done a jerry rigged repair of the shaft at some point and it was never documented, so nobody knew about the bearing until it failed. As a new low emission unit will be delivered in the next few months, there is no reason to repair 25. 25 will be put on display somewhere, perhaps near the Ferry Building, while 23 will be held as backup for the new unit.
But for now, an S2 built in 1944 is doing the job it was built to do. If you think about it, that is as though the Virginia and Truckee had still been using the Reno and Genoa during WW2.
Shorty after I got there, Ben went out and fired up the 23. It has a block heater, so it started easily with a puff of white smoke. He did an inspection of the engine, including checking the journal boxes. We then went back into the office and waited for Ryan, brakeman Johnny, and engineer Nick to arrive. The crew plotted their switching moves for the day. Ryan, who is yard operations manager, suggested that I get some blue hour photos from the ground as empties were switched and then we rode 23 while they switched loads.
Each car has dirt from one particular construction site and the dirt from sites cannot be mixed as different sites will have different contamination. UP ships it to a dump site in Nevada, where it is processed. Ryan explained that sometimes they can use dividers in a car to separate dirt from different projects if there is not that much.
Right now transshipping dirty dirt is the SF Bay's only business, but there a couple of other industries are interested in bringing new business. The line that crosses the Illinois St. bridge has been out of service for a couple of years as there currently no customers north of Islais Creek.
We rode the S2 for a while after the day brightened, then got down and Ryan drove me around in a company car to get some more angles as they switched. He then had other work to do and I shot the end of 23's work day as well as 25, some spare Alco parts and another project of Waste Solutions, goats that are leased out for natural weed control. Ryan said that since Waste Solutions got more cars, they can't use their goats as much for weed control in the yard as most of the yard tracks are occupied.
The crew called it a day for switching about 0800 and then would be doing other work in the yard for the rest of their work day.
All of these photos were taken with permission after signing a release and while wearing required PPE.
I want to than Ryan, Ben, Johnny and Nick for their hospitality. I had a great time.

For proper installation and proper root growth, special care and attention to detail should be observed. You can't just blow it u there's more to it than that in Sod Replacement
AR Maintenance Solutions in Lauderdale Lakes Removing old grass, plants and weeds under the grass root carpet is the first step. You cannot put grazing on the old grass. 2) Rebuild the substrate, adding fresh top layer will help replenish nutrients, support water absorption and increase root growth. 3) Leveling is required to determine varieties and ensure proper water separation to maintain. It is also used to remove high spots and fill the low places that remain moist or make the grass cut too short. 4) Nutrients/fertilizers can be added to support the grass root faster, but it is not always necessary. Be careful with fertilizers, they can cause burns to humans and plants if used incorrectly. 5) Donate - Install the new crack in parallel grain direction with latch, driveways or fences. The special practice of staggering parts is to ensure tighter seams and fewer gaps. This also makes it more resistant to animals and insects. 6) watering. If the new Lawn Correct is going to root correctly, the water must penetrate into the surface of the rollers and actually pass to the top layer of the soil below. If the watering requirements are met, the rough is guaranteed for 30 days. You will know when the crack will have enough water if the soil under the root carpet is constantly wet. It can be hard to know when there is enough water. A soil irrigation system is very useful because it can add water automatically if necessary

Wherever possible, we like to retain native grasses and shrubs that act as buffers to weed invasion at the bushland-pasture interface. Here we have been largely successful. In the places where we have not, we will have to stand by with herbicide to remove weedy competition from regenerating native plants if necessary. Careful monitoring will be necessary.
