Location Details/Description: John Muir National Historic Site, Martinez, CA.
The site is the home and fruit ranch once owned and managed by naturalist John Muir and is characterized by three separate park units: a 9 acres fruit orchard and ornamental garden site (House Unit); 350 acres of oak woodland and grassland (Mount Wanda Unit); 1 acre gravesite and orchard (Gravesite Unit). In addition to work at the John Muir NHS Members will also be engaged with the landscape at another park site located 20 miles away in the town of Danville, the Eugene O'Neill NHS, characterized by 15 acres of orchards and ornamental gardens.
For more information about Martinez or the John Muir NHS please visit:

Position Overview: The John Muir NHS maintains approximately 370 acres of landscape, in addition to 15 acres of orchards and cultivated landscape at our other park, Eugene O'Neill NHS. This position is necessary for our park to maintain the orchards, gardens, trees, shrubs and other landscape features to the quality and level expected by the public and the two park units. Currently the park does not have staffing to provide this level of service to the landscape and this position will meet and exceed that need, with supervision and guidance from the park Horticulturist/Arborist.

This position will entail a variety of landscape duties from basic gardening and cultural landscaping tasks (pruning, watering, weeding, mulching). Natural resource work may include removal of invasive weeds like thistle, threatened and endangered species monitoring, or native tree and plant monitoring. Day-to-day work will involve working primarily outside in a variety of weather conditions, though the timeframe of this position should be mostly warm to hot especially in summer. Work and tasks associated with this position may require the use of various landscaping hand tools such as pruners, loppers, rakes, shovels, hand saws, ladders, leaf blowers, lawnmowers, weed whackers, hedgers, fertilizer spreaders, (but no chainsaws). Power tools such as drills, screw guns, sanders, may also be required (but no chainsaw use at all). Use of ladders may also be necessary and proper ladder use/training will be provided. For any IPM (integrated pest management) work the Member may need to set traps or hand pull weeds, but any use of baits or chemicals will only be done under close supervision by the park IPM coordinator. The park philosophy towards toxic chemicals is to limit or avoid their use whenever possible in favor of mechanical or other means of pest management.

The ACE Member will likely work in a team of two but will also engage as much as possible with other divisions at the park including Maintenance, Natural Resources, Cultural Resources, Interpretation, and also park volunteers and Youth Conservation Corp members. To the degree possible, Members will be invited to engage with other parks in the Bay Area NPS network if time and opportunity allows. If the Member has time, interest, and initiative to take on special projects that interest them, and if such a project also aligns with park objectives, this would be supported by their supervisor. "Special projects" associated with these cross discipline opportunities could consist of either academic research into garden or landscape history of the sites or practical application of new plants or methods of landscape maintenance particularly as we are faced with maintaining the historic character of our cultural landscapes and plant palettes in the face of a warming and drying climate.

This individual placement is meant to facilitate professional development and promotes exposure to land management agencies and networking with professionals. This could include gaining experience in different conservation fields and shadowing different work groups.

Schedule: This will be a full-time 40 hour/week position, daily schedule will typically be from 7am - 3:30pm, however daily start/stop times may be flexible depending upon job assignments and/or the individual's needs on a day-to-day basis.
