Top 12 Outdoor Herbarium Materials for Building Enchanting Plant Displays
In the world of botanical research, preserving and studying specimens requires a variety of tools and techniques. Here are some essential items that make the process easier and more effective.
Monitoring Storage Environment
PH testing strips can be used to monitor storage environment acidity levels, ensuring the optimal conditions for specimen preservation. Temperature and humidity data loggers also prove useful for environmental monitoring.
Protecting Specimens
Heavy-duty zip-lock bags offer protection for delicate samples, while archival sleeves shield specimens from dust and insects. For added protection during handling, acid-free storage folders are ideal.
Pressing and Transporting Specimens
Adjustable straps or lightweight wooden boards create pressure in portable press systems, helping to prevent wilting and maintain specimen quality until transfer to a permanent press station. University Products herbarium boxes, featuring metal edges and acid-free construction buffered with 3% calcium carbonate, provide maximum protection during transport.
Controlling Moisture and Pests
Silica gel packets can be used to control moisture that attracts pests, while mothball alternatives like herbal sachets containing lavender, cedar, or rosemary can be used for pest control. Disposable dust masks rated N95 or higher should be used for specimen cleaning tasks.
Photographing and Documenting Specimens
A portable light box or photography tent helps control lighting conditions when photographing pressed specimens. A high-resolution digital camera with macro lens capabilities ensures detailed specimen documentation.
Examining and Measuring Specimens
A dissecting microscope with 10-40x magnification helps study surface features. Digital calipers are necessary for precise measurements of small plant parts, and a sturdy ruler with both metric and imperial units is essential. A compound microscope with up to 1000x magnification reveals cellular details.
Cleaning and Maintaining Specimens
Conservation-grade tweezers with fine tips are useful for handling delicate specimens. Microspatulas and fine brushes are necessary for careful specimen cleaning and maintenance. Nitrile gloves should be worn when handling specimens to prevent oil transfer from hands. Protective sleeve covers provide additional barrier protection during detailed work.
Safety Measures
Protective eyewear should be used when working with preservation chemicals or dust. Cotton lab coats should be used to protect clothing and specimens during handling.
Organizing Specimens
Large bags serve as primary carriers while smaller bags organize individual specimens. Genus covers help organize related specimens together.
Special Equipment
A portable press system allows immediate specimen preservation in the field. Diatomaceous earth can be used to create natural barriers against crawling pests. Sticky traps with pheromone lures can be used to monitor insect activity around cabinets. Clear polyester sheets (Mylar) provide visibility while preventing damage to mounted specimens.
Measuring and Mounting Specimens
Quality microscopes are vital for examining plant structures in detail. A sturdy tripod and remote shutter release help capture sharp, detailed images of small plant features. Adhesive solutions for herbarium specimens include methylcellulose paste, PVA glue, conservation-grade tape, and pH-neutral glue strips. Archival-quality repair tape is designed specifically for specimen restoration.
Field Collection
High-quality plastic bags in various sizes are useful for protecting specimens during field collection. A portable 10x hand lens is essential for quick field observations.
Conclusion
With these tools and techniques, researchers and hobbyists alike can effectively preserve, study, and organise botanical specimens, ensuring their longevity and the continued advancement of botanical knowledge.
