July Invasive Species Alert ⚠️ 🌿 Yellow Salsify: Grass-like with milky juice, grows up to one metre tall. Flower heads are pointed before opening. 🌿 Baby’s Breath: Reduces native grasses and forage for grazing animals. Can spread over 13,000 seeds per plant. Note: Often used in floral arrangements; avoid disposing of it in compost to prevent further spread. 🌿 Common Tansy: Can displace native vegetation. Infestations in rangeland can be toxic to livestock, and lead to dairy cattle having unpleasant tasting milk. 🌿 Cheatgrass: Alters wildfire regimes with its dense, dry growth. It can injure livestock and animals’ eyes and mouths with its sharp awns. Learn more about treatment options from our friends at @ISCBC or visit their website: bcinvasives.ca🌱

Aggressive growth, hard to kill, found in riparian areas, derelict land, roadsides, and gardens. Dedicated loads for disposal need to be managed as garbage. 🌿 Common Bugloss: Invades disturbed, sunny areas like roadsides and pastures, reducing crop yields. Leaves contain toxic alkaloid compounds, harmful if ingested by humans or livestock. 🌿 Common Burdock: Each plant can produce up to 16,000 seeds. Known for clinging burrs that attach to animals and can trap birds and bats. 🌿 Giant Hogweed: Extremely toxic plant with sap that can cause burns, blisters, scars or blindness. Can produce 50–100,000 winged seeds that float for up to three days. Needs to be bagged and disposed in garbage wearing PPE.

This invasive plant is a really doozy! 😫 The tree of heaven was added to our Noxious Weed Control bylaw last year. It grows quickly and produces by both seed and division. ⛏️ Young seedlings can be pulled or dug up, but cutting alone won't be effective due to it's aggressive suckering ability. However, repeated cutting can potentially exhaust root reserves. 💪 Learn more about best management practices in the fact sheet from @ISCBC: bcinvasives.ca/wp-content/up…
