Air Plants Wildlife Water Soil Resources and Climate Change Stewardship of Natural Resources Water Water Connects Us All All life forms require water for survival, so it doesn't matter whether you are a plant, an animal or a human, we are all connected by the need of water. We often don't think about it, but we are also all using the same water, as we all live on the same planet. Our Earth has the same water on it today as it did when the planet started. We do not lose old water, and we cannot get new water, it is the same water that has always been here, Its hard to believe, but the water you drink everyday could be water a dinosaur peed 80 million years ago! Fortunately, it doesn't taste like dinosaur pee, because our planet cleans and recycles the water for us over and over and has been doing this for millions of years. This process we call the water cycle, is often referred to as nature's recycling system, because the planet continuously cleans, filters and recycles water for us. However, this vital function can only continue if we do our part to help protect the environment and conserve our natural resources. We are often called the ‘Blue Planet’ because most of the Earth is covered in water. Actually, about 75% of the surface of the planet is covered in water, however 97% of all the water on the planet is in the oceans and is too salty to drink. That leaves only 3% that isn’t salty, but we can't even use all of that water. Temperature plays a very important role with the water cycle, as it causes water to change between the three states of matter (liquid, solid and gas). If the temperature is hot enough water will become a gas called water vapor. Water vapor is in the air all around us, we just can’t see it most of the time. Steam, fog and clouds. are good examples of water vapor that we can see. If the temperature is cold enough water will become a solid, in the form of ice. The polar ice caps (North Pole and South Pole) hold 2% of all the water on the planet, or 2/3 of all the fresh water. So, of the 3% of water on the planet that’s not salty, 2% of that water is frozen solid. That means only 1% of all the water on the planet can be easily used as fresh water. How humans use that 1% of water, can have a very long lasting effect on the water cycle and the stability of future generations. The Water Cycle Individuals and communities can help by reducing the amount of pollutants that enter our storm drain system and waterways, including washes, creeks, arroyos and ultimately the Santa Ana River. Since people, often unknowingly, generate the largest amount of storm water pollution, we can be the largest part of the solution. Find out more about how RCRCD can help educate you and others about these concepts, to help ensure that future generations will understand the importance of water as a vital resource and form lifelong habits that ensure its responsible use and care. Southern California Water Southern Californians depend upon two important sources of water: water that is imported from water-rich areas through extensive storage and transfer systems (canals and aqueducts) water that is pumped out of underground aquifers Aquifers are porous stone, sand, and other soil particles that store water underground. Water fills the pores, or air spaces between particles. Holes dug into aquifers (wells) fill with water, which can be pumped to the surface for our use. Locally and globally, underground water is being mined and depleted. Without adequate recharge, underground water levels drop. Recharge occurs when water is allowed to soak into the soil surface and percolate down to an aquifer. Roofs, streets, and parking lots prevent infiltration and hasten storm water through drains to local waterways, not allowing our aquifers to recharge. Communities can increase the amount of water that reaches aquifers by finding locations where hard surfaces, such as concrete and asphalt, can be replaced with permeable materials. Individuals and communities can also help by reducing the amount of pollutants that enter our storm drain system and waterways, including washes, creeks, arroyos and ultimately the Santa Ana River. Since people, often unknowingly, generate the largest amount of storm water pollution, we can be the largest part of the solution. Find out more about how RCRCD can help educate you and others about these concepts, to help ensure that future generations will understand the importance of water as a vital resource and form lifelong habits that ensure its responsible use and care. Local Water Water used within RCRCD’s boundaries is mainly groundwater from local aquifers. However, ground water cannot alone fulfill the needs of the Inland Empire region. Most groundwater is pumped by local public utilities; however, a few landowners have private wells. Riverside has holdings in the historic Gage Canal, which delivers ground water to most of the remaining citrus areas within the city. This source is of fair quality (420 ppm average total dissolved solids). The canal delivers 36,000-39,000 acre feet of water to the Arlington Heights area. Fifty-five percent of the water is delivered to citrus with the remaining 45 percent delivered to a City of Riverside Reservoir. Degraded water quality and contamination plague some local underground water sources. The Arlington basin has been abandoned due to high nitrate, MTB, and perchlorate levels. Riverside installed infrastructure to remove perchlorate from water extracted from contaminated wells. A reverse osmosis desalination plant is currently operating in the basin to produce a domestic quality supply and to help clean underground water. Colorado River Aqueduct In addition, some communities rely on Colorado River water and the State Water Project to meet needs. Amounts of imported water vary from year to year. The California State Water Project, delivered chiefly for domestic uses, began with a small increment in late 1979. Metropolitan Water District is the wholesaler of state water, which is normally provided to Western Municipal Water District (WMWD) and other communities. During the latest and worst drought on record, the City of Riverside sold water from underground sources to WMWD.

Along with bees, pollinators can include birds, bats, butterflies, moths, flies, beetles, wasps, and small mammals. A pollinator can be any animal that visits flowers to drink nectar or feed off of pollen and ends up transporting or moving pollen grains elsewhere. Bright, sweet-smelling flowers attract pollinators. which feed on the nectar produced by these flowers, brushing up against the flower's pollen. When the pollinator moves on to another flower, it takes the pollen with it, transporting it to where it needs to be (the part of a plant called a stigma) in order for the plant to reproduce, to produce seeds and fruits . Why Are Pollinators Important? Pollinators are essential to our daily life. They are responsible for bringing us one out of every three bites of food. Pollinators also sustain our ecosystems and produce our natural resources by helping plants reproduce. Pollinating animals travel from plant to plant carrying pollen on their bodies in a vital interaction that allows the transfer of genetic material critical to the reproductive system of most flowering plants – the very plants that bring us countless fruits, vegetables, and nuts, produce ½ of the world’s oils, fibers and raw materials; prevent soil erosion, increase carbon sequestration For more detailed information on the process of pollination click here . According to Pollinator Partnership , "Somewhere between 75% and 95% of all flowering plants on the earth need help with pollination – they need pollinators. Pollinators provide pollination services to over 180,000 different plant species and more than 1200 crops. If we want to talk dollars and cents, pollinators add 217 billion dollars to the global economy, and honey bees alone are responsible for between 1.2 and 5.4 billion dollars in agricultural productivity in the United States. In addition to the food that we eat, pollinators support healthy ecosystems that clean the air, stabilize soils, protect from severe weather, and support other wildlife." These are just some of the foods we would lose if pollinators were to disappear: Honey Tree fruits such as apples, peaches, apricots, plums, lemons, limes and cherries Bananas, melons, mangos and papaya Berries such as strawberries, blueberries, elderberries, blackberries, raspberries and cranberries Onions Almonds, cashews and coconut Avocados Bean varieties such as green beans, adzuki, kidney and lima beans Coffee Tea plants Vanilla Sunflower and sesame oils Tomatoes Cucumbers Grapes (and, therefore, wine!) Cauliflower, cabbage, broccoli, turnips and Brussels sprouts Beetroot, pumpkin Chocolate Sugarcane Agave Pollinators Are In Trouble But You Can Help Why Are Pollinators In Trouble? Pollinator populations are changing and many are in decline. Loss of feeding and nesting habitat is a large part of the problem. However, the overuse of chemicals, especially as pesticides in gardens and agriculture, along with pollution, disease and climate change are also contributing factors to the shrinking populations. How You Can Help? Everyone can help pollinators, and the more people that get involved, the better the chance our pollinators will have. Adding pollinator-friendly habitat is one of the most significant things each of us can do. Having a small home garden, planting pollinator friendly plants on farms, at schools, in corporate landscapes or even in public spaces all can mage a big impact. Pollinators don’t seem to be phased by city life, as long as there are plots and patches of flowers and food for them to find. Please come visit our LandUse Learning Center or click here for ecoregional planting guides to learn more about pollinator friendly plant species. Or visit our publication on Steps for Success for Milkweed and Monarchs for the Inland SoCal Valleys , for more specific information on how you can help Monarch butterflies. Adding natural habitat or pollinator gardening near community gardens and farm systems can also increases urban agricultural yields. Having farm hedgerows can also increase beneficial insect activity. A hedgerow is a farm practice used in sustainable agriculture to increase beneficial insect activity, help control erosion and weeds, and foster biodiversity. Basically a variety of native plants are grown at the edge of a farm field including species that are known to be attractive to beneficial insects and that provide flowers and cover over the course of a year. Hedgerows may include trees, shrubs, perennial grasses, rushes, and sedges. Come see our hedgerow adjacent to the Ag Area at the LandUse Learning Center. Some species of local plants that are appropriate for hedgerows in our area are listed below. For more information, see Establishing Hedgerows on Farms in California . Other things that you can do to help: Spread the word about the importance of pollinators. Support Farmers and Beekeepers by buying local honey and locally produced organic foods. Reduce or eliminate the impact of pesticides whenever possible. If home owners, local governments, national governments, and private industries all make an effort, we can have a positive impact for pollinators also helping to secure our own future.

As a part of assessing land for conservation, the RCRCD examines the health of any habitat existing on that land. During this survey RCRCD determines whether the existing habitat is in excellent condition, could benefit from some improvement, or is in need of repair. The goal of all projects is to provide healthy functioning habitat that can be sustainably maintained in perpetuity. The RCRCD conducts habitat enhancement projects to improve certain aspects of habitat, such as by removing weeds in slightly infested areas. Once initial enhancement activities are complete, the habitat often begins improving naturally, although follow up treatments are conducted to ensure the infestation doesn’t return. Habitat restoration is conducted by the RCRCD in areas where there is significant damage to existing habitat and it isn’t likely to recover without significant help. Restoration projects involve more significant improvements than enhancement ones, and consist of removing weeds, site prep, native plant installation, and irrigation and maintenance for several years. Restoration and enhancement are the two types of projects that the RCRCD conducts most frequently. Monarch caterpillars on milkweed planted at restoration site There is another type of project, habitat creation, that the RCRCD will occasionally conduct. This type of project is quite uncommon as it is difficult to create the environment for a new type of habitat in an area where it doesn’t already exist. When it is possible, RCRCD generally conducts these types of projects in areas where stream courses have been widened or other places where the hydrology of a site can sustainably be altered. Although many of the RCRCD enhancement, restoration, and creation projects are for riparian and associated habitat types such as willow mulefat scrub, alluvial scrub, and oak woodland, some projects are conducted in other habitats or for the benefit of specific plant or animal species.

Urban growth within the District has put pressure on remaining areas suitable for wildlife. Direct loss of habitat, the diversion of streams for municipal water supplies, increased effluent discharge, and intensified recreational use of open space has adverse impacts on wildlife populations. Here are some of the ways the RCRCD works to protect native species ( per Divison 9 of the California Public Resources Code Article 1 Policy 9001 Section B Article 3 & 4 ) : Provide BMP information and assistance to land users to assist with habitat management. Promote exotic, invasive species control and removal from landscaping. Propagate and release Southern California native fish, aquatic reptiles, and amphibians, as funding becomes available. Develop the “Greenbelt” research facility with fish raceways plus indoor/ outdoor tank storage for quarantine, and short term fish and amphibian care Create appropriate habitats at RCRCD facilities to support native wildlife. Install nest boxes and watering facilities in RCRCD habitat areas as needed. Install wildlife cameras at RCRCD facilities, corridor crossings and select nest boxes to monitor local wildlife. Aquatics Research, Propagation and Restoration The RCRCD conducts a variety of restoration and research projects in an effort to increase fish and amphibian populations in their native ranges, mainly in the Santa Ana River Watershed.

The Riverside-Corona Resource Conservation District (RCRCD) provides free technical assistance to "cooperators", and property owners who are interested in conserving their natural resources, per Divison 9 of the California Public Resources Code Article 1 Policy 9001 Section B Article 4 . Farmers, homeowners, and businesses of the greater Riverside area may be eligible to receive free irrigation evaluations or other resource assistance. The Conservation District has conducted over 1,000 evaluations on more than 10,000 acres since 1987. The RCRCD's Irrigation Water Management (IWM) Mobile Lab auditor evaluates irrigated sites with operational systems. Irrigation systems are tested for uniformity and efficiency of water delivery. Is water reaching the intended plants? If applied too broadly , water is wasted on adjacent surfaces, such as sidewalks, streets, or parking lots. Over spray may be the result of incorrect spray adjustment or arc selection. If applied too deeply , water moves below the root zone and is lost from plants. If applied too quickly , water may runoff the surface before it can infiltrate into the soil. Runoff often causes erosion, which creates sediment, a pollutant to local waterways. Most runoff is not from the soil surface but from water being applied to hardscapes. Is water applied evenly and uniformly? Auditor examining water sample Inefficient water use is often the result of leaky, clogged, or worn components or incorrectly installed pipes and sprinklers. Well-designed systems become less effective when mismatched replacement parts are used and when systems are not maintained. Water pressure is measured to determine its effect on sprinkler and emitter output. Misting may indicate that pressure is too high, while a doughnut shaped water pattern may mean that pressure is too low. An auditor analyzes system effectiveness, looking for problems such as uneven water distribution. The auditor considers site conditions including system output, plant water-requirements, timing of irrigation, and weather data. The onsite evaluation determines soil conditions and cultural practices that affect irrigation. A report is developed based on field test data, soils, and weather data. The report indicates potential water savings, deep percolation losses, and maintenance needs. Scheduling an Audit: Testing sprinkler head output For questions or to schedule an audit, please contact Jose Iniguez at [email protected] . Audtis are conducted on properties with an irrigation system that waters a half acre or more . Evaluations will be provided free of charge if your property lies within the RCRCD boundaries or within the service area of Riverside Public Utilities (RPU) and meets the water audit criteria. Evaluations include a system uniformity test, soil test and results report.
