1. Collecting specimens: Specimens can be collected by carefully removing a plant or animal from its natural habitat without causing damage. It is important to document the location, date, and any other relevant information about the specimen.

2. Pressing and drying plants: Plants are typically pressed between sheets of absorbent paper and dried in a plant press. This process helps preserve the plant's structure and color.

3. Mounting specimens: Once dried, plants are mounted on herbarium sheets using glue or tape. Labels with information about the specimen are also attached to the sheet.

4. Preserving animals: Animals can be preserved in a variety of ways, including through taxidermy, freeze-drying, or preserving in alcohol or formalin.

5. Cataloging specimens: Each specimen is assigned a unique identifier and entered into a database along with relevant information such as species name, location, and collector.

6. Storage: Specimens are stored in a climate-controlled environment to prevent deterioration. Proper storage conditions help ensure the longevity of the specimens.

7. Digitization: Many herbariums are now digitizing their collections, making them accessible online for research and education purposes. This involves photographing specimens and entering data into digital databases.

Herbarium Techniques for Collecting Plant Specimens

1. Field Preparation:

- Equip yourself with a vasculum (plant press), plant label tags, a ruler/measuring tape, a notebook, and a pen/pencil.
- Choose healthy and representative plant specimens with mature plant structures (leaves, flowers, fruits).
- Select specimens that showcase the plant's unique features and variations.

2. Pressing and Drying:

- Place the plant specimens between sheets of absorbent newspaper or blotting paper.
- Insert a label tag with the plant name, collection date, collector's name, and any other relevant information.
- Position the plant specimens to flatten and preserve their essential features.
- Stack the pressed specimens in the vasculum, alternating layers of specimens and absorbent paper.
- Secure the vasculum with straps and place it in a warm, dry, and well-ventilated area.

3. Mounting:

- After drying, carefully remove the specimens from the absorbent paper.
- Trim the edges of the specimens and arrange them on herbarium paper.
- Secure the specimens with acid-free glue or tape.
- Add additional notes, such as habitat information, plant use, or any relevant observations.

Herbarium Techniques for Collecting Animal Specimens

1. Field Preparation:

- Equip yourself with appropriate collecting equipment (nets, traps, containers, preservatives).
- Identify the target animal species and research their specific collection protocols.
- Handle animals carefully and ethically.

2. Collection:

- Use appropriate techniques to capture or observe the animals, depending on the species.
- Record data about the animal, such as species, sex, age, and collection location.
- Preserve the animals using appropriate methods (e.g., ethanol for invertebrates, formalin for vertebrates).

3. Storage:

- Label and store the animal specimens in appropriate containers.
- Use preservative fluids or freeze specimens for long-term storage.
- Keep specimens in a cool, dark, and dry environment to minimize degradation.

Additional Considerations for Both Plant and Animal Collections:

- Obtain necessary permits and ethical approvals for collecting.
- Respect the environment and minimize disturbance during collection.
- Protect specimens from damage and contamination during handling and storage.
- Document all collection activities, including dates, locations, methods, and any observations.
- Share collected specimens and data with scientific institutions and researchers for future studies.
