Had an amazing time at this year's @presidiosf Planting Day! We successfully planted around 2,000 plants including many types of bunch grasses and forbs, which are flowering plants that lack woody stems. #consbioUSFCA #conservation #presidio

Although mangrove habitats have been targets for deforestation, that has decreased significantly in recent years. There is still a lot of work ahead though, as each individual mangrove system faces different threats! https://t.co/WjdnYApLS9

Cleaning off your shoes with these devices throughout the Presidio is a great way to help prevent the spread of plant pathogens. To the the extra step, you can also spray off the soles of your shoes with ethanol! #consbioUSFCA #conservation #presidio

A couple weeks ago on 11/12, I volunteered with the Presidio to plant almost 1,000 plants at the Fort Scott Parade Ground. We planted many 26 different, native plants, 4 of which were native grasses! #consbioUSFCA #conservation #nativeplants

English Ivy is an invasive species in California. They can grow very tall, affecting building infrastructure if they grow on walls, and block sunlight from other plants for photosynthesis.

Planting native plants, weeding, and spreading compost at this past Saturday's @presidiosf habitat stewards event! The compost spread here will hopefully help plants grow where the soil is compact! #consbioUSFCA #conservation #nativeplants

The Sacramento River suffered due to human activity. Restoration efforts by the Nature Conservancy include replacing orchards with the river's historic riparian landscape, and more. Over 6,000 acres of floodplain habitat have been recovered! #consbioUSFCA https://t.co/cb4YDYTVhn

Removing Himalayan blackberry with @presidiosf at the Fort Scott Community Garden this past Friday during their forest stewards event! The Himalayan blackberry is a pesky nonnative species, and are spread throughout the garden

The global increase in temperatures is detrimentally affecting plant pollen by destroying its proteins, hindering reproduction. This has been observed in many plants, including crops grown for human consumption.

A success story of species reintroduction is the bald eagle on the Channel Islands. Due to DDT exposure, they disappeared from the islands in the 50's. Bald eagles from Alaska were used to repopulate the islands, and there are now 40! Image via:NPS/IWS

A very common invasive species in California is French Broom, found in coastal areas, the Sierra Nevada foothills, SF bay area, and more. It forms dense patches, preventing native plant growth. Many animals also will not eat it. Image: Joseph DiTomaso via Cal-IPC #consbioUSFCA

While the ongoing climate crisis is often viewed from ecological and financial lenses, it can have severe consequences on physical health too. One consequence is life-threatening heat stroke due to exceedingly hot temperatures. https://t.co/SQ3CgE3xAL #consbioUSFCA #climatecrisis

The Break Free From Plastic Act of 2021-2022 was introduced to the senate last year, and if passed would reduce pollution from plastic manufacturing, reduce single use plastics, hold companies accountable for their plastic production, amongst other actions. #consbioUSFCA #BFFPA

Australia, a hotspot for mammal extinction, has launched a program called the Threatened Species Act aiming to prevent new extinctions. This new program also includes First Nations People in the management of threatened species. #consbioUSFCA #conservation https://t.co/cUFnKGwngg

Was taking the Caltrain this weekend and spotted eucalyptus on the side of the track. Despite living in California my entire life, I never knew that they aren't native Californian species! Eucalyptus was originally introduced in California for timber! #consbioUSFCA #conservation

[Ally Halliday @AllyHalliday23]

Removed lots of English ivy and irrigation from an @presidiosf site this past Friday! English ivy is an invasive species in California and can grow extremely high on native redwood trees, sapping nutrients from them #consbioUSFCA #ecology #conservation

[Ally Halliday @AllyHalliday23]

Saw an ice plant on my way to volunteer today and
I remembered that I learned in conservation biology that they are a non-native species. They can be found all over the coast of California and unfortunately outcompete many native Californian species! #consbioUSFCA #iceplants

[Ally Halliday @AllyHalliday23]

Had a fulfilling day volunteering with @presidiosf at Quartermaster Reach Marsh removing weeds like buckhorn plantain! Also got to work on restoring the native sand dune systems which helps combat soil erosion! #consbioUSFCA #conservation #ecology

While today Crissy Field is filled with grasses and trails, it wasn't always like that! Crissy Field was once a military airbase, but was restored to a national park that many once endangered birds like herons now call home! https://t.co/WUkXDSZCTU
