Aquatic Plants?

By Tony Tomeo

Meet Scooby

Our Pet of the Week for this week is a real cutie- a guinea pig named Scooby! He is one year and 4 months old and has been at the Shelter for a few months.

He is s sweet and furry friend who likes carrots and squeaks for more snacks! Scooby can be shy at first but after time and attention he can be a lovely little companion and addition to your home.

Guinea pigs can be great pets and with the right care and patience they are fun and social animals. If you are interested in meeting Scooby or any of our adoptable animals stop by the Shelter!

Adoptions are first come, first served! Please view available animals on our website and then visit the Shelter to turn in your application. All adoptions require proof of home ownership or landlord approval. Please have this information prepared. If an animal is in Foster Care, please bring in your adoption application and schedule an appointment to meet the animal. Call 831-454-7200 x0 during business hours or visit www.scanimalshelter.org for more information! n ••• Santa Cruz County Animal Shelter’s full-service, open-admission shelter:

American History

© Statepoint Media Home gardens and landscapes should be compatible with their respective climates. For local chaparral climates, plants that do not need much watering through the long and dry summers are appropriate. Aquatic plants are the extreme opposite. They require regular replenishment of the ponds that they inhabit. Arid warmth increases their need for water.

Aquatic plants can not be ‘drought tolerant.’ Several, such as duckweed, water lettuce and water hyacinth, float over the surface of water. Water lily and lotus inhabit the mud below the water, and extend their foliage to float over the surface of the water. Waterweeds stay completely submerged, with or without roots. Aquatic plants need water for their survival.

Marginally aquatic plants are somewhat less dependent on water. Cattail and yellow flag iris inhabit shallow ponds and saturated soil, but can survive if their situations drain for a while. If they stay too dry for too long, they can initiate dormancy, and then recover when saturation resumes. Canna inhabits either shores of shallow ponds, or evenly moist soil.

Regardless, all aquatic plants require maintenance that is completely different from what terrestrial plants require. Even those that need only minimal maintenance will eventually necessitate muddy and messy interaction. Much of such interaction is under water that is difficult to see through while murky. Aquatic plants are innately heavy and totally sloppy.

Moreover, some common aquatic plants grow like weeds. Water hyacinth and giant reed are two of the most invasive exotic species in California. So, not only are they sloppy, but they are also voluminous! Because they are very invasive, they should not inhabit ponds they could escape. Besides, giant reed is too overwhelming for most home gardens. Few home gardens include natural ponds or water sources to contain as ponds. Garden ponds are therefore mostly contained within some sort of sealed infrastructure, and need replenishment to compensate for evaporation. Fountains aerate the water for a healthier ecosystem, but also increase evaporation. Some tall aquatic plants also consume water, as the foliage that extends above water transpires. •••

Duckweed

Ducks somehow find water. They eventually visit most home garden ponds they can fit into. Duckweed, Lemna minor, is likely to come with them. It adheres to waterfowl and other wildlife for that purpose. It proliferates very efficiently, and almost typically becomes a nuisance. Eventually, proliferation in a healthy pond should stabilize to a tolerable rate.

Individual duckweed plants are tiny. Their oval leaves are typically less than a quarter of an inch long. Each floating leaf extends its single root less than three quarters of an inch into the water below. Plants produce no more than four rooted leaves before dividing into a few smaller plants to repeat the process. Bloom and subsequent seed are uncommon.

As a floating aquatic plant, prolific duckweed might obscure koi and submergent aquatic plants within garden ponds. However, it also helps stabilize healthy aquatic ecosystems. In fact, it is useful for bioremediation of agricultural and industrial applications. It absorbs detrimental substances from water, while producing fodder and biomass for composting. n •••
